Jive read people using the wipers or distributor. Also seen a few things at car shows being tied Into other connectors like this. But what's the right way? Running 11ga with a fuse to the battery or into the fuse box?
Here's the way I did mine.
New oil pressure sending unit was like $12. Wiring an electric choke
I also added a TEE so I could use the dash idiot light, and add another sending unit for a gauge to be added later.
Dont listen to anyone that tells you to wire up your choke to the distributor.
You can use the exciter wire from the alternator (only gets juice when alt is spinning), the yellow(?) Wiper motor wire, or any other SWITCHED 12v source, preferably fused. On the 231 Buick at least, GM had the choke tied in with the oil pressure switch. It would close the circuit at a preset limit (usually something low like 5psi). That set up used the tan wire from the fuse box, brown to the idiot light (r vise versa, dont remember exactly what goes where), and a light blue wire to the choke itself.
