ECU box wiring for '86

[gumba]

There seem to be 4 primary wires coming from the ECU box wiring loom, red, red w/green stripe, black, yellow. Red to the battery, red w/green stripe & black to the fuse panel. So where does the yellow one go? The motor won't start, there is fuel and power to the coil and cranks fine. This is for an '86 3.2 which now resides in my '68 V.W. Crewcab.
Thanks

Yellow usually goes to the starter solenoid.

To test, put the Red and Black directly to the battery (a fuse between is nice insurance). You want to be certain that while cranking the positive juice is still getting to the DME (ECU)

Red is to the battery
Green/Red is 12V out to the fuel pump from the DME relay (term 87b)
One black is 12V switched to the DME relay term 86
Not sure what yellow you are referring to there is one that gives switched 12V to DME, another to the O2 sensor (this is probably only on CA cars with the heated o2 sensor.)

Sorry should have stated one yellow wire is the cranking signal, originates from the ignition switch to the DME pin #4 (so gives 12V only during cranking)

Thanks for the help, one down. The next problem seems to be no power to the DME relay. The relay seems to be powered by #86. Following that line leads to the "contral switch" which I don't believe I have. Will 12v from the fuse panel work to #86 work?

Term 30 needs battery voltage, term 86 needs 12V switched power that must be present during cranking.

Thanks, got it running.
