Trip minder install

Ok so I have gotten an trip minder out of an older Tbird. Has anyone tried to hook one of them up to are cars?



Pin 1: EMPTY
Pin 2: EMPTY
Pin 3: Ignition Power (light blue/black stripe)
Pin 4: Dimmer (light blue/red stripe)
Pin 5: Power (light green/yellow stripe)
Pin 6: Data output line (DOL) Fuel Flow Input (light blue/pink stripe)
Pin 7: Ground (black)
Pin 8: Speed Input (dark green/white stripe)
Pin 9: Ground (black)

Really it is a simple install I just don't have a pin out of the connector on the pcm.
So I guess I'm asking if any one has a pin out for a 91 SC pcm.

91 SC 5 Speed: 3" drop springs, 10% OD blower pulley, 3.5" cold air intake, C&L 85mm MAF, MP 85mm TB, KW double IC, Walbro 255 lph fuel pump, #42 injectors, Mach One hood, saleen mustang wing, Solid Rubber Motor & TransmissionMounts, Autodown Windows, Auto open moonroof, March underdrive pullies Plug and play key less entry module.

I found this pin out. Is this the same as on my 91 SC for the most part? I'm interested in pin 34.

Seems like it ought to work though I doubt that the SC ECM pinout is the same.

For what it's worth, you might think twice about spending too much time installing that. The one in my Fox Bird was about as accurate as a... uh... not very accurate thing.

I wasn't thinking about a permanent install. More or less just something to mess with to see what it says. I can run all but 2 of the wires from the radio. I just need to run the speed sensor and dol wires.

I think that would be pretty cool to put in if it was accurate.

Well you never know how well it works untell you try. And thats all I want to do is try it out. So I still need a pcm pinout.

It's doable with a 89-93 N/A 3.8 or 5.0 since the PCM uses the same data feed as the digital cluster(pin 34 DOL with EEC IV), 4.6 and SC PCMs don't have the pins active so you'll be getting 200 MPG lol. All of the other circuits are there.

The speed part is dead on accurate from when I tested mine, I imagine MPG is fairly accurate as well considering the fuel calculation's done through the PCM from injector duty cycle.

I added one to my friends 89 ranger. We had to run a wire to the pcm since it didn't have a wire in pin 34. So I'm just trying to find a pin out so I can even see if the sc computer has a DOL.

It would be pin 34 in a SC PCM as well, it will be under NOT USED in a pinout and won't be active with its calibration since the SC never had a disco dash.

Well the ranger never used pin 34 and it work just fine on it. So I hope its the same on the sc. If not o well it was just something to experiment with.

The Ranger likely shared the same hardware calibration with the aerostar which did have a digital dash option. You could get lucky, but the SC hardware is pretty unique to itself and is doubtful the DOL pin would be active.
