1970 Chevelle Pro Touring Build

[David LaBuda]

This winter I plan on redoing the entire electrical system. This includes building new fuse panels for the interior and engine compartment. I don't like how bulky the Camaro harness is under the hood and while the EZ interior harness works, it doesn't fit very well and it doesn't have enough circuits. I plan on using four of the Cooper Bussmann fuse/relay panels and a couple of their power relay modules. This would give me room for 40 fuses and 20 relays which had better be enough!

I was able to reverse engineer some of the factory wiring diagrams to figure out how the flashers, steering column harness, and ignition switch work. Once I figure out how to distribute the power to each circuit I should be pretty well set. I've included a couple pictures of my sketches but I'm not sure how readable the are. (I am a mechanical engineer by the way, so cut me some slack haha)

The ecu will be relocated next to the engine bay fuse panel because I HATE having to fish the entire harness through the firewall. I would like to have a large weather tight plug to connect the ecu power wires (injectors, coils, ecu, etc) to the fuse panel. I'll also have a large bulkhead connector on the firewall for body wiring (lights, wipers, engine sensors, etc).

David did you check to see if Ron Francis already makes what you need??? (shameless plug for sponsor)

I'm sure they do, but I can't justify spending $500 on something I can build myself exactly the way I want it.
