ok i bought a 05 ls2 gto engine harness... well i bought a cam sensor and cam sensor harness for a 05-06 gto from gm. they mate just fine.. but i cant get the cam sensor harness to plug into the engine harness.. its like the clips wont mate.. is there any differances between 05 and 06 gto engine harnesses.. i cant remember if i ordered the cam sensor and harness for an 05 or 06 gto. thought they were the same anyways .. any ideas thanks
