HEI in a 71 GTO wiring question
 

I have the HEI in the motor and now working on the wiring for it. I have read several posts about the pink and yellow wires at the ignition switch. Today I crawled under the dash and got to the ignition switch. On my 71 there is no yellow wire at the switch, pink yes, yellow no. What do I do now guys? Is there an alternative to this method? I have run a 12 gauge wire into the passenger compartment from the HEI, just need to tie it in correctly.

I think 1970 was the last year for the yellow wire at the switch

Thanks everyone!!!!

If your car has an IGN terminal at the fusebox, plug it in to that.

I ran mine to the fuse box ignition terminal.
OG68 beat me to it.

OK , will have to look for that. I gather there is no ING1 and ING2 at the switch? I guess I am making sure there is 12 volts at cranking and at the on position of the switch at all times.

Sorry Guys I am not a good electrician.

Thanks everyone!!! Made up my harness and plugged it in. HEI is now live.
