When I bought my '78 Camaro last summer it had a Rochester 4 barrel Carburetor with an electric choke on it. The power was supplied to the electric choke from a large red wire with weird plug on it. When I say large wire, I'm talking about a wire that's between 1/8" and 3/16" thick with the red coating on it.

It has no power until the key is turned to the run position. I didn't check to see if it had power when turned back to the radio on position.

I want to make this into a "power block" for accessories requiring 12 volts while the car is running like my electric choke, my Volt Meter Gauge and any thing else I might need accessory power only when the car is running.

How does this sound? Does anyone know what this wire was originally used for?

I also have two small blue wires that seem to have been cut on the drivers side of the firewall a little bit lower then the steering column and in more towards the transmission hump.

Probably elec choke feed and I would leave it for elec choke.
Supply power for other accessories, I would run a separate power block from the fuse panel thus keeping current through the IGN contacts of the ign switch to a minimum.

They used a wire that thick for the electric choke? And wouldn't that wire come off the fuse panel somehow? If not, where would you hook my aftermarket volt gauge to?
I was told to splice into one of the orange wires (running lights wire I guess) in the dash/gauge panel area to hook my lights for my aftermarket gauges to.

Thanks, NYH1!

Big question is if it's powered during ACC or IGN power. You don't want your electric choke powered while listening to the radio. Chances are if it's a bonafide choke power lead then it's an IGN power source and may not be what you're looking for.

Using a relay to provide an ACC (or IGN) power distribution point is a great idea. Just be sure to provide proper fusing for the loads you derive from your new power source and you'll be fine.
