FiTech EFI system
I also covered the few single wires aft of the plug with 1/8th braided nylon sleeving that I bought from Grainger, heat shrink covers the ends and ties things up neatly.
Someone asked about the fused section of harness.
When I ran it on the driver side along the intake/valve cover the plug was awkwardly exiting. On my small block routing it around the front then back along the passenger side valve cover/intake crease it tucked neatly beneath the coil.
I cut a section of rubber hose to cover the exposed wires leaving the fused sections out. I then electrical taped the ends and middle to clean it up as best as possible.
The red battery hot lead goes to the starter relay constant hot terminal from my battery
I ran the white lead from the FiTech to one side of my ballast resister, (since I am running an MSD I can bypass the ballast) I then used 2 piggy back spade terminal connectors to connect both sides of my ballast (Start and run)
