How to wire up an electric choke

How about this, will this work? I swapped my car from AC to non AC but the compressor wire is still there. Can I run my choke to the compressor wire? If so, should it be the thicker wire or thinner one? Would look good using "stock" wiring.

I got a multimeter and went into the fuse box under the steering wheel. Found a live spot without a fuse which got 12v with ignition on and 0v with it off. Think it was the fuse spot for the ac which has been deleted. Ran a cable from there through the firewall, then by the back of the firewall, under and behind the distributor, to the choke. Zip tied it loosely to the vacuum hose so it wouldn't be hanging freely. Now, I don't know if it's wrong or not, but that's how I did it, and it works perfectly.

The other red (or pink maybe?) cable goes to the battery spot on the distributor. But it had been like that since I bought the car. After the pic I routed it with the new choke cable and zip tied everything in a clean fashion.

You did it right, just make sure you put the ground wire on it

I pretty much did it the same way. Ran a wire from the switched +12 volt source on the fuse panel and also added an inline fuse before connecting to the choke.
Turna is right, an electric choke Holley will need a lead to ground. With a Q-jet, make sure there's no gasket between the (electric) choke pod and carb, or else the choke will not operate properly.

These come with a ground that is attached to a bolt on the body of the carburetor. So it should ground itself to the engine since it is bolted onto the metal manifold.

Assuming there's a ground from the engine to the chassis and from the chassis to the battery.

I have found many electrical issues coming from people not reinstalling the engine to chassis ground, or the battery to chassis ground, apparently thinking a cable from engine to battery is all that's needed.

I'm gonna have to look into that and redo my grounds then. Cause the previous owner ran a whole bunch of cables to a bolt on the intake manifold. Thanks for the tip.

I had an open spot on my fuse panel under the steering wheel that i plugged the wire into. Then ground to the firewall
