1976 Trans Am Resto-Mod

I finally did enough research on the wiring for my car that I was able to start eliminating wires from my ECU and cleaning up the wiring harness. My goal is to make the engine ECU a stand alone harness. There are many companies that do this, but most charge around $500 to do. I have spend around 120 bucks for the Bussmann relay box and all of the metri-pack connections for a factory style feel.

I have decided that I will utilize the hole in the firewall that is behind the passenger side cylinder head to route the ecu inside the car. I think it will make for a cleaner build. I will also put my fuses and relay box inside as well. I plan to mount them behind the center console similar to where they were mounted in 1981 where the CCC was located.

I started by pulling the pin retainer caps off of the two large connectors that go to the ECU.



I got the factory Pin-outs online and took out the pins that were no longer needed, there were about 20 pins that I was able to take out of both connectors.





You can see all of the pins that I pulled back from the main bundle of wires.



Now, I am not sure why this was done, but the cam position sensor, had an extension connector with another 2 feet of wiring? So I de-pinned the connectors, and put the correct Cam Position sensor end on the pig-tails.



Here is where I am currently, and I am starting to bundle the wires and recreating my harness. I need to finalize the layout and hook-up the fuse and relays to make everything work correctly.



And here is a pile of wires that I was able to delete for the system.



That is all for now. Lots more wiring to come.
