Default RE: How To: Repin your harness

Your lucky I did this for everyone lol

[align=center]Wiring a P series VAM into a 88-90 Mustang
(this is for when your doing a 2.3 turbo swap with a computer other than a LA, LB, 8UA series)



[/align]Splice into/”T’’ connect the VRef (orange/white) to the wire going to pin 26 of the stock harness (also orange/white). (I say splice into/”T” connect the wire running into the engine bay. This is because pin 26 is being used by the TPS, MAP, and EGR.)




Remove Pin Connector #3 from LX wire harness red block (or take one from your harness you salvaged, and put this pin connector and wire into the red block of your LX harness to plug into your Pin 43 position on the P series computer. The LX harness lacks this connecting pin).



Connect the VAF (white/black) to the wire going to pin 43 of the stock harness (the new connecting pin you just put in)




Connect the VAT (vain air temp) to pin connector #27 (this can be found at your EGR Valve position sensor) Now move that pin #27 to pin #25 and move #25 to an area with no pin (this is the ACT sensor which only the PE, and 87-88 turbo coupe computers can use)




Splice into/"T" connect the VAM signal return (black/white) wire into the LX harness (black/white) wire that goes to pin 46. Do not cut the LX harness (black/white) wire going into pin 46, simply connect this VAM signal return black/white wire to it.

93 is differant. This is site for the 93 notice Sleepers is for 88-90.
I read your closed thread. If you didn't find the info.
1st Read this site and reread many have messed up on it.

It is not difficult just read and reread. Most problems occur with "T" wires. This means you take a wire and splice into it another wire. You wind up with 3 wires connected. NOT 2 wires together and a loose one. Good luck. Maurice

Default ???

This makes ZERO sense to me???

All I see is 4 wires. The black one is connected (T'd into) a wire in the harness and the rest of the wires do what???

It doesn't show where to connect on either end of the 3 wires?! Am I missing something???
