I am in the process of a 3.4 swap. I am also switching from the auto t-case to dual gear driven cases. While looking at the wiring harness that runs onto the transmission and t-case, I noticed that there are 8 wires and 4 connectors that normally attach to the auto t-case, that won't attach to the gear driven cases.

My question is....if I remove those wires that attach to the t-case, will it throw a CEL or will it be okay. Is there anyway to bypass it if it does throw the code? Can I just pull the pins from the wiring harness connector at the ECU?

 

top. Help please

 

A couple of the wires are for the neutral safety switch, two wires are for the back up lights, and the other wires are for the shift solenoids, you will need to jump the neutral safety switch wires for the truck to start, then figure out witch two wires are for the back up lights, and the other wires won`t be used. You can also remove the transmission computer because it will no longer be needed with the manual transmission.
