Exclamation Help with wiring: Coyote 5.0 Swap

Hey guys, I will fully admit, I'm not the best when it comes to wiring. So I need some help.

In this picture, I need help with the Blunt Lead 1. I need to connect the Red/Light Green Wire to the Ignition Switch Position.

Second, on Blunt Lead 3. I need to connect the Red/Light Blue wire to the start node of the ignition to switch.



(*If non-PCM controlled starting is used, step 8.2 C may be omitted, and unused blunt leads should be cut to ~2”
length and sealed using heat shrink.)

I have a Ford Electrical manual, I took a picture of the ignition switch diagram.



Let me know what you guys think,

Josh

A. Blunt Lead 1: just tap that into the most accessible circuit R/LG (16) circuit, since the power distributioon box is underhood I'd tap it there

C. Blunt Lead 3: I assume "non-PCM controlled starting" means regular key start rather than pushbutton/keyless start? The circuit in our cars runs from the ignition switch, to the MLPS(or clutch switch on 5 speed SCs) and turns into a white/pink wire that runs to the starter solenoid, so assuming "non-PCM controlled starting" does mean regular key start you should be able to omit it. It seems that the PCM is to apply the voltage to trigger the solenoid rather than the switch, or you can have an either/or scenario and just splice it in-line(if you retrofitted the remote/button) .

So for blunt lead 1: Let me type it out so I can better understand. The battery provides 12 volts to the t-bird PDB, it is hot at all times. The BK/O wire provides 12 volts to the ignition switch and it is also hot at all times. When I put my key in the ignition and turn it over to Start/RUN, 12 volts is provided to the R/LG wire. I need to connect the blunt lead 1 R/LG to the R/LG wire coming from the ignition switch?

Blunt lead 3, I get that now, that is for a remote or button switch. derp.

Yes after the ignition switch the R/LG wire only gets 12v in the start or run position, so as long as you tap it somewhere in that specific circuit you're good to go. Looking on the EVTM page you can see the section of the arc between run and start is darkened - that means those two positions are connected internally - so whether the key is in run, R/LG is getting 12v, or whether the key is held in start, R/LG is getting 12v.
