Default Question re: TCS wires and HEI

I'm finishing up installing new harnesses (engine and dash) on my '70. The car has a ZZ4 engine with an HEI distributor. My question is that since I am not using the TCS relay are the 2 black/pink wires a good place to tap into for HEI bat and the electric choke?

TIA
Jim

Those are 20 gauge wires,thats pretty small considering GM fed the HEI with a 12 gauge wire and it was unfused (except for a fusible link).

Thanks Roger. Looks like I better look elsewhere. Don't want to burn up a new harness.

I always go inside to the 12 pink coming off the ignition switch and tap in using a large scotchlock ,then roll up the resistor wire in the engine compartment in case someone wants to go back to points.

Thanks, I'll check that out. I guess I was trying to take the easy way out. At my age I try to spend as little time as possible under the dash.

OK,well there is another possibility that you can try. Just under your throttle cable engine side are 2 wires (pink and green)that go to the backup light switch on a 4 speed car. You can use the pink for power,Ive used it on Pertronix installs but I've never tried it on the HEI.

If that will keep me from standing on my head I'll give it a try.
