Does anybody know?I have the whole dash harness here and I want to know what I can chop off and what I need.



Thanks

Luis



FYI-I have pics of the harness but they are huge

 

Heres a similar plug except mine is a 88 setup and not sure if the wires are the same colors(haven't checked yet)



Look at the plug as it were pluged in the ECU.

Upper bank from left to right



B/Y - Hazard Heat swith

BR/Y - Trailing coil ignitor

BR/R - Port air solinoid valve

W - 1st Crank sensor,These 4 wires are (Big Gray wire sheilded) and grounded

L/B - Service light

L/R - Coil trailing

B/R - Shift light

B/L - Split air solinoid valve

G/B - Nutral switch

L/O - Fan relay

BR/Y - Air bypass

Y/B - Check conector



Lower bank



L/Y - Coil ignitor trailing

G/Y - Coil ignitor leading

R - 2nd Crank sensor

LG - Knock controll

L - 3rd Crank sensor

G - 4th Crank sensor

Y/L - Clutch switch

O - Check conector

BR - Water temp

L/W - Air con main relay

Y - Check conector

Y/R - Check conector



Could you tell me the info on these wires that I need to hook up and which ones I don't?And where under the dash they go?



Thanks

I figured it out for the most part of it.



Main harness wiring(S4 T2)

Look at the plug as it were pluged in the ECU.

The pins on the 87 harness are the same location however the colors might be different than the ones shown.
