Hello!
I need some assistance on wiring. I have a 1970 W31 that was previously converted to an HEI. I'm having it converted back to the correct points distributor and coil.
1) The car has a factory tach which currently works off of the HEI, what side of the coil +/- will the tach wire hook up to?
2) The coil bracket has a small radio noise condenser mounted to it where does that wire connect to? The coil +/-
I've checked the wiring diagrams that I could locate and I'm unable to get a clear answer. Thanks for any assistance!

 

The tach wire goes to the negative stud on the coil, and I’m pretty sure the condenser is also on the same stud.

 

Thank you much appreciated!

 

Don't forget you need to install a resistance wire from the bulkhead connector to the coil+ and a resistance bypass wire from the starter I terminal to the coil+ terminal.

 

Thank you Eric! - not sure what's left in the original harness there is some taping so hopefully we can see the remains of the original wires

 

If the harness is all hacked up it might be a good time to get a new harness under the hood. It's a good investment and well worth the money.

 

I'm considering that - thanks for the response!
