1972 Wire ID help

[Glen C.]

I"m slowing working my way through wiring clean-up and I have this single tan wire that I can't id. It seems to originate towards the center of the fire wall. Would anyone know what this goes to? Any help would be greatly appreciated.

Thanks,

Glen

pretty sure that is the idle solenoid wire.
my 72 BB had that wire coming out from the TCS harness.

I agree with Bill. My 72 small block has the same color wire, and same type wire connector, going to the carburetor solenoid.

Yep. For sure, Bill and Lawrence have nailed it. The wire is supposed to run to the solenoid, held against the inboard edge of the LH rocker cover.

Hope this helps.

Thanks everyone. I'll get it sorted out now that I know what it is.

Glen, saw your last post this morning and remembered I had some pics of my engine without air cleaner can on it. It shows the tan wire's routing. I assume it's TFP, since the car's been judged several times this way, however, if someone sees something out of order, please let me know. Hope this helps.

That's one nice looking engine compartment, Don!

Re: 1972 Wire ID help

Thanks Don. That is a great looking engine compartment for sure. It appears that one of my previous owners has removed the solenoid. The fellow I bought my car from had the engine rebuilt and I got boxes of all the old parts he removed. I hope it's in one of them. I'll check today.

Again thanks for the photo it helps a lot,

Don,

I dug through the boxes of replaced parts that came with my car and found the solenoid. The previous owner rebuilt the engine so I guess he just removed it. I think it's original as it looks a bit worse for wear. Is there a method to test it operation prior to re-installing it?

Thanks,

Glen

Re: 1972 Wire ID help

I simply grounded the body of the solenoid and put 12 volts to the male power connector to verify mine operated. I believe the tan wire should have 12 volts when the ignition key is on.

Re: 1972 Wire ID help

I agree with Dan. This is how I tested mine too. Hope this helps.
