Wiring - Electrical Connectors and Circuits

So, I guess I'm in territory that most people have not entered. I'm in the process of going through my wiring harness and changing the flex loom and adding shrink tubing and things like that and I also want to prune out the things I won't need since I'm building a "racecar". Anyway, I'm smarter than the average bear and I already have the Ford shop manual and EVTM for my car and I figured that I would just refer to that for most of my needs. Guess what? Ford/Helm does not provide diagrams/pictures for most of the under hood connectors.

Does anyone know if there is a source for this kind of information? I also have these manuals electronically and neither has these diagrams/pictures.

I realize that I can figure it out by tracing the wire colors and making educated guesses as to the connectors and find them in the EVTM but that's going to be a major PITA.

TIA

dDUBb mentioned he has factory drawing different than What I have, which sounds like what you have, the EVTM and Helm book.

I've never noticed them being missing.

But I bet Matt has. Let's see what he says; I added in wires for stuff from the EEC to the engine harness from C197 ( I think, the big one) but haven't dealt with the other ones.

The connectors are named by number in the EVTM, such as c197, and if you flip to the back sections of the EVTM each connector has a location index with description and sometimes a pinout diagram in the in-line connectors section

Correct. However, there is no picture/diagram of said connector. There is only the picture of the engine bay and the base location of the connector. It's not the case for all connectors but things like TPS, ECT, ACT/IAT, Fuel Injectors, etc. are not shown at the connector level.

I'll just have to back into by cataloging the wire color combos for each connector and then walking through the EVTM to find out what they are. I can tell the obvious ones but things like the AC controls and Air Injection are not things I need but I don't the connector by sight.

Since I'm finding some things and not others, I'll post some of my challenges here to see if you guys have some insight.

The first harness that I'm mapping out is the one that has all of the fuel injectors. If you guys could help me figure some of these out I would appreciate it.

2 pin connector - BR/PK and R - EGR Vacuum
2 pin connector - W/R and R - Air Injection Bypass
2 pin connector - LG/R - GY/R - ECT
4 pin connector - BK/W, GY/R, BK/LG - EGR Solenoid
8 pin connector - R, Y/W, BR/GR, GY/W, BR/W, GY/R, BR/R, GR/R - ????
4 pin connector - T/W, BK/GR, GY/Y, GY/R - ????
1 pin connector - R/PK x 2 - ????
2 pin connector - GY/R,R/PK - ????
3 pin connector - GY, W/R, GR/W - ????
1 pin connector - W/R - Oil Pressure Sender
8 pin connector - LB, GR/PK, T/BK, BR/LB, W/Y, T
8 2 pin connectors - Fuel Injection Connectors - I'm good here
3 pin connector - TPS - I'm good here

I have some vague ideas on some of these. I know that the TFI connection is in there.

TIA

Edited to say that my paper EVTM apparently is missing Cell 150. In the electronic version there is a cell 150. That contains the connector diagrams. So far I'm not finding any matches from a wire color perspective.

Just an update.

I've managed to document a lot of the connectors and junctions. I updated my resurrection thread with pics of the fuel injection harness being in place. I've managed to document all of the connectors on the other half of the engine harness that goes to the ECM. I just need to clean all of the connectors and redo the wire loom on it as well as remove the unneeded connectors/wires.

It's disappointing that the EVTM doesn't show most of the under hood connectors but it is what it is. There are so many useless connectors in there; from the AC to the EGR and Air Injection to all of the VMM connections for a VMM the car never had. It's interesting.

On a side note for those of you that have the EVTM in electronic format; it's a 16-bit app so you can run it on 32-bit versions of Windows but not 64-bit. Even 32-bit Windows 10 works just fine. The reason for this is that it requires NTVDM which is the "virtual machine" required for 16-bit apps and that function is not allowed in 64-bit versions of Windows.

I just had a thought on this; I think you are going about this the wrong way, and you should try starting from the ECM connector pinout diagram. That will tell you what circuit each wire is, what color it is, and what connector number it goes to. Then if you are still unsure, you can look up the pinout for that connector number to confirm that it is what you have in your hand. Since you don't have to worry about any wiring for factory gauges or climate control, you should be able to easily identify everything you need to run the engine, and remove everything else.

Also, just a side note for any other wiring you may be adding in for aftermarket gauges and such, Ford Explorers and Rangers, and probably some other vehicles as well, have a couple nice square bolt-together weatherproof connectors sitting right above the intake manifold, that each have in the neighborhood of 20 wires going through them. Rather than having multiple things wired separately, and multiple locations of passing wires through grommets through the firewall, if you cut these connectors out of car in the junkyard, you can run all the extra wiring though that, and have one connector and one harness for all added on wiring. Since we were running an Explorer motor and harness, we ran everything through these connectors, so when we had to swap a motor at the track, the only electrical connections we had to worry about were the 2 main connectors on top of the intake, and disconnecting the trigger wire from the starter.

It would be helpful to have one of these … it has the connector end view and pinouts for every wire on the entire vehicle. I have one for a 1994 Thunderbird - not sure what year your car is, but they are very specific to the vehicle year. I didn't even buy this one - it was given to me by a local guy who sold his Tbird and thought I might have some use for it.

It wouldn't be too much trouble for me to take pictures, but I believe if your car is not a 1994, a lot of these connectors would be different.

I have been able to trace out connector pinouts using the EVTM by wire color / circuit ID number even when the end view was not displayed in the EVTM previously, but I can understand where it can get confusing. The good thing about the way Ford did the circuit ID, is that the color / circuit number is pretty consistent across model / years.

That's the pix I referred to above; do you have a link, or know where they can be ordered?

Better yet, a part number printed on there somewhere?

Oh, yeah. I have the entire pin out map for the ECM. It's all in the EVTM but none of that tells you what each connector is without mapping out the individual wires. Also, a lot of the connectors in this system don't wire back to the EVTM.

It's fine, I've generally figured it out.

Also, outside of the main engine harness, I'm trying to prune out a lot of the wiring so that I won't need to pass all of this stuff back through the firewall to the interior.

I have all of that. In fact, I have more than that. I have the Helm EVTM and Shop Manual as well as the wiring schematic sheets which are large format along with the electronic versions of these. I guess I need to look at the large sheet diagrams closer because it does have the connector pics.

I wonder whether we're using the same program.

With the CD I have, the vac section works with my W10 Pro 64, but the wiring portion uses a separate .js and Winblows is giving me database errors for some reason. I'm not finding the prob with Notepad++, but I was sure I had everything working under W8/.1 before the upgrade. I haven't done anything electrical in a long time, and didn't even try to view the schemo with W10 before reading this thread.

Ebay possibly .. mine was donated from a local Tbird owner. The part number is on the front .. FPS-xxx just substitute the 94 for your year. In my case, I only own 94/95 Super coupes, so its convenient that they are identical.

Aha that is great news .. I was under the impression from your original post that you only had the EVTM and Shop manual. The Car wiring diagrams have all of the connector end views if you don't mind combing through the spaghetti maze with a magnifying glass to find where the splices are.

Yeah, I don't mind. I had the schematics buried in the cabinet in the garage and I just hadn't pulled them out because, for some dumb reason, I figured they were just bigger, nicer versions of what was in the EVTM and the electronic versions. It's (not) funny how they are three very different versions of similar things.

My whole reason for doing a lot of this is to clean up the wiring that is there. All of the pollution control connectors and other stuff just needs to go from the system. I've got the time and the initiative so I'll just get it figured out. The schematics are truly the missing piece.

Sometimes I just need to put the words out here to get my brain stimulated to solve the problem. That's the whole point of this place, right?

OK, the fun continues.

The wiring schematics are the actual godsend. However, I have a slight issue.

Engine Coolant Temp Sensor - LG/R - GY/R
Water Temp Sensor - GY/R - R/W
Water Temp Switch - R - R/W

The last two only show up on the schematics and I definitely have those connectors. They appear to link up to the instrument cluster (gone) but I can't find them in either version of the EVTM.

Am I just going crazy or is this more complicated than necessary?

The coolant temp LG/R goes all the way back to the eec on my 96; pin 38.

It also goes thru the big connector.

This also says GY/R is a ground at the instrument cluster.
That makes sense, it's shared between the two sensors.
GY/R comes from the secondary junction block to the instrument cluster.
It hits the vss, EEC,evo, and the fuel pump sender.

R/W only goes to the gauge, it looks like.

Yeah, the ECT (LG/R) definitely goes back to the ECM. I guess it explains why I couldn't use the stock wiring to get my new water temp gauge to work. It's several different leads. Oh well. I'll drop it and wire the gauge directly. We'll see though. I may reuse some of that wire and pass it through the harness.

2According to my 1993 EVTM … 5.0 engine EEC page 25-3 - The ECT is fed by a common wire ( signal, usually 5 volts reference ) GY/R from the EEC which supplies power to all of the sensors via and return signal to the EEC is LG/R ( this is where the EEC reads the voltage )

Page 62-1, Performance I am assuming ? .. the temp gauge in the dash is fed 12 volts ( hot / run, R/Y to the power distribution block in the dash ) .. grounded through the GY/R and the ECT sender on the engine is the signal wire to the temp gauge in the dash via the R/W signal wire.


Not sure of any water temp switches except for the Cold engine lockout switch ( 55-3) and that's a Y/W


The R/W is for the temp gauge / temp sensor in the dash … any wire that is solid Red is 12 volts in start / run … not sure why that would be wired to an on/off switch, that would make your temp gauge basically useless.

I think I'm not helping, you guys are eec4, and my wiring is different.

Its about the same as far as basic functions / instrumentation / wire coloring / circuit ID goes. They just added more sensors to the EEC-V PCM.

OK, that all makes perfect sense. Thanks.

There is a lot to digest in general so this is a great sounding board when I run into these things.

You guys are all performing exactly as I had hoped.

LOL thanks .. Im glad our college Degrees in Electrical are useful to you, because they are basically useless in my day to day profession.

That's good. I work in IT for a living and I feel like those skills aren't as useful as they used to be these days.

Skills are what you use them for; I have talents that never get used except for me, and then someone else finds out, and it goes from there.

I showed people how to solder 0201's this week; I can't really see them without a stereo microscope, lol.

I really hate lead free solder, tho.


If I'm calculating aerodynamics, it's for me, and a test case the software I have doesn't cover, lol.


I showed a nephew how math in the classroom connects to the real world, and got a note sent home to not make the other kids feel bad.

This is what I showed him:

Easy Gearhead Calculus:

Position is where you are. {x,y}

You want to go to the end of the dragstrip. X+N(mi),Y

How fast you went is T(seconds)=X+N(mi), Y

Σ(X+N)/T is how fast you went average across the distance. (10 seconds is 40mph, lol. That's if you were going an even speed over 1/4 mi.)

Velocity is the first derivative of position.

Since a real drag race doesn't work that way, you get to Acceleration.

Acceleration is the second derivative of position... and it's a function of HP/RPM/W (Weight). And you have other stuff too:

HP/RPM, Gearing, Tires, slipping, wheelbounce, and all with respect to the mass of the vehicle; all the gains and losses are their own functions.

So just simple math can take you some great places; these days you can model the tire flex, with the right programs.

My uncle has acceleration data every 0.01 second, and that's a great way to sort out problems with traction, etc.

Next challenge. I want to get rid of the fuse block under the hood in favor of something else. There are tons of fuse boxes out there but I have yet to run across one that supports the high amp fuses that are used and I need 6 of those. They range from 30A to 80A.

Any tips?

I don't see anything out there that's as good as our block; Nothing with the big fuses at all.

Working with Ralph and Matt on IRC, we found a good alternative: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

OK, so, I may as well just add this to this thread.

I have a bit of a problem. I don't have any place to pass the large round wiring harness through the firewall. This is the big two part junction that bolts together through the firewall. I've attached some pictures of the areas next to the firewall so you can see my problem.

I'm open to thoughts.
