Need help identifying 12v wire for electric choke

[Truck82]

Hey everyone! I am installing an electric choke on my carb and know very little about electrical. The manual that came with the choke says to connect the wire from choke to the yellow/black wire going to the wiper motor. As seen in the picture, there is a yellow and a black wire. Does this mean I can use either one? It needs to be connected to the ignition so it turns on with the truck

What carb are you using?

The choke power wire can be the one that went to the original choke coil. If that wiring is gone or in bad shape, run a wire from a fused ignition terminal in the fuse box (there's usually an extra) and to the new choke.

You can leave the wiper harness alone, there's no reason to tamper with that.

I usually just run a wire from the 12V IGN Terminal in the Fuse Box to the Choke. Works great. Just need to find a place to snake it through the firewall.

Shouldn’t there already be a wire that comes from the oil pressure sending unit? Unless it’s gone for some reason.

I only know because when I got my truck, the wiring was a disaster. Apparently the choke gets power after oil pressure is sensed, then receives power.
