What is this wire?

I have a 1969 that came factory with a 327 2 barrell, powerglide and factory air. The car has not ran since 1977 and the motor is locked up. I pulled the engine and dropped in a 400 sbc for now. There is a single red wire on the drivers side that is a pretty large gauge. I checked it and it has 12 volts when the ignition is on, I thought about using it for an HEI distributor but I would at least like to know what it went to, I can't remember, I must be getting old. Any info would be appreciated. Thanks, Charlie

Re: What is this wire?

copy this and blow it up and you will find all the wires you 'might' have. Its all in the AIM which you should have if restoring an old camaro. Assembly Instruction Manual, available from our site sponsor, ebay, other resto companies also carry it.

Re: What is this wire?

More than likely, it is the wire for the carburetor idle-up solenoid. Does it have or did it have that asphalt type sheathing on it, and have a straight push on connection?

Re: What is this wire?

Yes, but it is on the wrong side of the carburetor.

Re: What is this wire?

What did it plug into from the factory (the carburetor, intake?) Also, it is long enough to wrap around to the other side of the carb. I do not want to cut anything because I will eventually put the original 327 2 barrell back in the car. Thanks for your input.

Re: What is this wire?

Charlie, thats what it most likely is as Amptech stated; the wire that connects to the fast idle solenoid on the drivers side of the carb.

Re: What is this wire?

The solenoid should be coming from the harness along the firewall by the wiper motor and the plastic wire gutter molding that is on the firewall. It would follow the driver side valve cover to connect to the solenoid.

Re: What is this wire?

I was always told and have had the understanding that that soleniod was an anti-dieseling soleniod. When voltage was applied to it (key on) this soleniod magnatized the coil and made the plunger retract. When voltage was removed (key off) the plunger returned to its correct position which in turned opened the throttle a little and made the carb shoot a small amount off fuel into the engine, which would prevent the engine from!!!! Dieseling, running backwards and all those funny sounds it would do.

I think you have it backwards. When power is applied the solenoid operates opening the throttle blades a bit more and setting the engines idle. When you shut the engine off, power is removed to the solenoid and the throttle blades close keeping the engine from running on. Most run on (dieseling) is caused from the throttle being held open too far when the engine is shut off... There are other causes but they are associated with age and crud buildup in the cyl head...

Re: What is this wire?

That's exactly what that red wire is for - that solenoid whatevertheheckitsfor - on the carb. My 307 2 barrel had it, and it was original. It now feeds my distributor.
