Re: EEC IV Wiring Help Needed.
AREA 4
Gray Yellow…………….Hot on accessory
Black \ White……………Neutral Sensing
Tan \ Lt. Green………….Fuel pump relay
Red (I think)……………Inertia switch
Area 1
EEC Power Relay
Orange and Black wire splice into Red wire from pin 57
Red wire from relay to EEC is pin 37 and is correct
Black/Orange goes to pin 1 and too fuse link to starter relay!!!! NOT BATTERY
Black/Lt. Green go to battery ground terminal, also pin 40 on the EEC
Red/Lt. Green tap into your ignition coil wire, TFI Module, and to a fuseable link.
AREA 2 I heard that the wire color codes can very a little depending on supply at the time the harnesses were made.
AREA 3 The fuel pump relay did change locations
AREA 4 Green connector by the EEC From what I can tell is that they are going into the computer.
I hope the info helps, I had a friend at a drafting company blow the wiring diagrams up onto 3 foot by 4 foot drawings. Much easier to read. Good luck.
