Wiring harness Question
Reworking my harness and have a couple questions. The engine is an 02 lq4. Its going in an 86 chevy truck backed by a th400 non lock up transmission. I'm using a 99 wiring harness from a 4.8. Is there any reason why I can't remove all the wires from the harness that have anything to do with the electronic controlled tranny? Does TCC=Torque Converter Control? Do I have to run a vss?

I would ask The guy that did/is doing the ECU, I know they can delete alot of the extra BS stuff in the computer for a swap like you are doing

the vss is used to control the timing tables. if not youre more then likely be stuck in the idle timing table

you should talk to Jared @ Current Performance Wiring
