Are you talking about just the engine/trans harness, or all of it? If all of it, I could help you out.

 

it would be everything. i want to move the fuse box into the cab and ecu.. dont want anything under the hood

 

I'm talking about deleting the bcm. Moving **** is not rewiring.

 

During my LS6 swap we pulled out my engine harness lengthened and shortened accordingly and ran it down and around the back of the motor. I really like the way it turned out. Be sure to solder and heat shrink all your connections so you don't have any issues down the road.

 

^^ That looks awesome.

 

I been there before, relocated Ecu and Tcm inside the cab. I don't know about older style cab if the fuse box any different than nnbs. It not that hard but its time consuming. On 2007 nnbs the fuse box has plugs that disconnect from underneath basically the ecu and tcm are connected in same wiring harness and rest is body wiring headlights & etc.

Buy a Labeller and Helping hands You Thank me later

Label the wire twice and check twice then cut the wire in between.
Do it one by one because there is allot of of wires that look alike. Good Luck and keep us posted

On the Link below pg7 you see what you have to deal with Ecm & Tcm Only
