HEI Installation

[geezer#99]

No ballast resistor. A resistance wire comes from the ignition and is spliced together with the yellow wire to the coil and another yellow wire to the starter solenoid. You need to replace the resistance wire with a 10 gauge wire and disconnect the yellow wire at the solenoid.
You can you use the existing spot the resistance wire plugs in to the power block on the firewall or run your 10 gauge wire to an unfused 12 volt connector on your fuse block.

My engine wiring harness is newer and is nicely wrapped thereby preventing me from following EACH wire. Going back to the power block on the firewall, I see a purple wire that I'm assuming is the one that also goes to the solenoid but I don't see a yellow wire at that point. So I simply disconnect the yellow wire at the solenoid and then run the 10 gauge wire from that point on the solenoid to an unfused 12V connector on the fuse block (that is only hot when the ignition is on)? What relationship does the purple wire have that is connected to the other side of the solenoid?

Thanks for the information. I very much appreciate the responses!

the purple wire is to activate the starter with the key!leave it, its important!
the wire you are looking for on the engine side of the firewall wiring block should be white and its preferable to replace this one if you can.
