Finished my 78 SC Engine, but fool that I am did not label the wiring harness...

There are 3 square spring-clip connectors that I cannot determine exactly where they go... I prefer not to play Russian roulette...

The wire codes are as follows:

1) Brown and brown/red

2) Yellow/Blue and Red/Black and Yellow

3) Red/white and brown

I can't find a wiring diagram that shows them...

Anybody have any idea which device gets which?

Thanks

On my 1979, I see four. One goes to the auxiliary air regulator (over the right side valve cover), one goes to the warm up regulator, one goes to the cold start valve, and one goes to the safety switch on the back of the throttle body.

Sorry, all my wires are snuggly hidden under their rubber cover and I can't see them, but the connectors are all different colors. Silver/grey on the WUR, black on the AAR, light blue/green on the safety switch, and a darker blue/green on the CSV. Is the 1978 not the same?

One of the advantages of digital cameras these days,--shoot everything BEFORE you start a tear down.

According to the Current flow diagram in my factory manual

y/blue and r/black goes to-- fuses on the rear fuse box (regulator side

red brown--- below regulator panel

red/white and brown looks like ----- thermo valve

hope i read this correctly and it helps. Worst care situation I can have the pages copies and send them to you. There are 2 of them about 12x20 inch. Or you can call me while you are looking at the car and I can look at the book at the same time.

Is it installed yet? I screwed up mine and what happened was it would start but not run unless the fuel pump relay was jumped.

The gray lead goes to the WUR. One of the black one goes to the AAR. Length wise, if you have a short run going to the fuel controller, it is probably the one that goes to the AAR. Remaining is the cold start valve.

Good luck.
