I can't find the thread know but was there a problem with the wiring on extension harness for the cam sensor, that two of the wires on the front cover had to be changed for a ls2 in a f body. Not sure if this is true or not, but I thought I had read this in a previous post that people were having problems with that

Its on the ext harness that the wires were wrong.I swapped the red and the brown up where it plugs into the firewall on the harness.On the sides of the plug it has A-B-C for the wires,See if both sides of the harness match.I forget what color wire matched up with the letters...............Paul
