I am putting my toy together cause I need to drive it. I have and '89 Chevy truck. It had a TBI 350 so I yanked the TBI intake heads and swapped in a set of Summit heads and a performer rpm intake. I didn't hack any wires so there all still there. I can't seem to find the keyed hot wire since I installed a HEI distributor I know it wont just pop on but if anyone out there could take a picture of the correct plug and give me a color I would be extremely appreciative!

 

I can't remember where I tapped in on my s10 blazer when I did my swap but you can run a fresh wire to the IGN on the fuse box if need be.

FYI, it is never a 'keyed hot wire'. It is either one or the other, never both.

 

Use the heavy gauge pink wire that hooked up to the factory tbi coil. Run this to your distributor and you will be fine and not have to run any new wires.
