The yellow wire goes back to the coil to boost the distributor voltage during the starting sequence to a full 12 volts. After starting the distributor voltage runs through the resistance wire dropping it down a few volts. You can hook it up and see if it makes a difference.
I was tucking my wiring away tonight, and I could NOT for the life of me remember what I ran this yellow wire to the starter for. Thanks Hokie! I have one sad wire hanging over my fender teasing my swiss cheese brain.
I know, I need to stop pulling up these OLD posts, but, i've found so much great stuff on here, that I have not been able to find anywhere else, I like to say thanks!
