For people who did an engine harness tuck. I was wondering how did you guys hide your wires that leads into the cabin to the ecu? I'm trying to visualize it and do an engine harness tuck but its so hard to find a sweet hiding spot for the engine harness that connects to the harness that goes to the ecu. Some of my buddy told me to run the wire behind the tranny bracket. Any pictures that shows how the wire is tucked would help tremendously.

 

The majority of people remove the heater core right by the back mount and run it through there .
