Stroker's Build (5.3/4L60E in a '69)

[OneOffStroker]

Wiring ran through the firewall. The ECM, TAC, fuses and relays are all mounted under the dash. This seriously cuts down on visible wires under hood. Looking at the passenger's side of the motor, all of the wiring is hooked up and you can hardly see it. I still need to loom the driver's side, obviously. I like that there is just one 6" bundle connecting the engine to the firewall.

I will also be rewiring the entire truck with an EZ-Wiring harness. I plan to run all of those wires in/under the fenders and inner fenders so that it will be minimally visible as well. Once all of the sheet metal is painted bright white, this should be one seriously clean engine bay.
