HEI Distributor Wiring

I would say that you need to replace your fuse box, it looks pretty rusty.

Unless you have a tachometer you should only have one wire going to your HEI distributor, and it should be connected to the "Batt" terminal. (the "BATT" & "TACH" terminals should be marked on the distributor cap).....

I would go about this differently. I would replace the wire that went to the coil in the engine harness where it plugs into the fuse block. All the resistor wire is on the engine side. Crimp a type 56 connector onto your new HEI wire and swap it in the block. You can get type 56 connectors at NAPA, CarQuest, GM Dealer, Ebay, etc. Just be sure to disconnect the yellow wire on the starter.

I second this. That's what I did on my conversion. Very simple and I didn't have to run any wires through the firewall. Just replaced that resistor wire and put the right terminal on it and done.

Which wire on the fuse block went to the coil?

I installed a HEI distributor on my 1972 C10 several years ago and I believe we connected the yellow wire going to the coil to the BATT terminal on the distributor while the yellow wire is still connected to the starter's "R" post.

Does this mean that I am getting less than 12 volts to the distributor when running?

I just noticed this today after replacing the starter. I left the yellow wire off the starter and the truck started just fine but I haven't driven it yet.

Please advise.
