So over the past year i have been building my 2005 GTO. I took the old LS2 engine out of it and replaced it with a TREPerformance LQ9 408 iron block stroker, i am in the final steps of finishing it and have run into the problem of the knock sensors being under the intake in the valley cover. I am still running the Ls2 harness and have done resurce and seen that people tap and drill the block but unfortunately i have the engine in the car already and don't have the time to take it back out and have it drilled and tapped. is there any way i can make a custom harness through splicing new plug into the harness or is there a conversion harness out there for GENIV to GEN III.


Please help and any tips are welcome! Thank you.

Run an extension harness from the LS2 harness to the knock sensors in the valley... Use one normally used to convert the other way. They are available.

Or delete them in the tune.

All you need to do is connect the wires to the sensors in the block is 5 minutes.

You maybe able to peel back the harness for extra wire length with out adding another piece.

Yeah, wasn't trying to be a smartass, usually Google can be VERY good to find info. But sometimes.....
Actually CAMSTER has a good idea. Just extend the wires to where they will reach. No big deal. Good luck my friend!
