Identify electrical wired

I have a 1972 cutlass. I am replacing the engine wire harness. I can’t figure out where this black and yellow wire connects to.

Where do these wires attach to? 1972 cutlass engine harness

Where do these wires attach to?

Those go to the "+" terminal of the original ignition coil. Should we assume you have HEI now?

EDIT: I can see the HEI distributor in the photo.

Yup. There's 12v on it so it's a good idea to tape up the terminal end and then secure it so it can't flop around and ground itself.

I believe the ignition wire that is coming from the fuse box. It’s connected to what is labeled “battery” on the distributor.
