electrical question

[71_bowtie]

I'm working on a 56 chevy and using a 70 chevy fuse panel in it. The engine is a baby 400 from a 78 jimmy, so it has HEI. My question is....there is a heavy pink wire from the 70 fuse panel that goes thru to the engine and changes to a yellow wire that goes to small terminal on starter and also to the coil. With the HEI the small terminal isnt used and the coil is in the cap. so would the pink wire go to the bat terminal on the HEI ? i'm sorry if this all sounds confusing. any help would be awesome. and i do have wiring diagrams for the 56, the 70-71, and jimmy.

Pink wire should stay pink. It comes from the ignition switch and goes to HEI. Yellow wire should go from key to neutral safety switch or clutch switch, then purple goes from there to starter.

If the harness is a 70 then there is no power wire for the hei 75 was the first year for hei.I would add a relay to power the hei so it gets full 12 volts

What I would do is just fold and tape that wire in case I ever wanted to run a point distributor again and run a 10 gage wire from the keyed pin on the fuse box to the hEI using the correct HEI connector on the distributor end. Female slides come loose at inopportune times on those.

On my 71 I plugged the 10 gage wire into the pin that is circled on the diagram below. I've run it that way for over two years. I just folded the stock ignition wires that ran to the coil back to the harness and taped them up. They don't do anything and are there if I decide to go back to a point style distributor.

Yep. That's what I get for answering while almost napping. No HEI supply wire in '70.
