I heard you have to alter the cam sensor wiring with an LS1 to LS2 swap. If so, can any one tell me what needs to be done to the wiring.

 

Maybe, it is a crap shoot. Swap the two outer wires.

 

That is what has to be done. You can buy a pig tail that is all ready done, for you it is what i did.

 

I ahve used 8-10 of them form three different sources and about half are right out of the box. Not sure what the mystery is. If it is wrong it will pop and fart but probably run and you will get the sensor fault. Then just flip the wires.

 

Thanks for the help. I'll try that tonight.

 

I lucked out and mine (Katech) was correct.
