4+3 wiring for '85
there are 4 electrical connections on my 4+3 trans.
one into the trans which is the left in this pic. one into the o/d unit, the right in this pic.
another single wire into the o/d unit which comes from up in the shifter area and the last one which i believe is the speedo connection into the tailshaft.
what i need to know is what colour wires run to each connection. i "accidentally" snipped these wires off a while ago while doing my carb conversion and can't remember what is what. my service manual is absolutely no help.
agent86 sent me a wiring diagram a long time ago, but my crappy computer won't open it.
anyone have any insight
thanks

wire diagrams
go to checker or autozone, and buy the cheapie Haynes manual. the wiring diagram is in the back.
I think there's a color code in there for the wires as well as circuit numbers.
geez, don't even buy it. bring a pen and paper...........

From front to back of car:
1st gear switch = black/white & lt blue
Reverse gear switch = dk blue & lt green
Overdrive enable = dark green
VSS = yellow & purple
You can wire the switches either way, it doesn't matter.

Yellow / purple to VSS in tailshaft
Green to O/d solenoid
Lt green / Dk blue to backup light switch
If you have a carb then no need for the 1st gear indicator on side cover , is input for ECM only
