Default Cam Sensor Problem

I am swapping a LS2 shortblock into my 98 Trans Am, only a few days from completion I decided to test out the Katech conversion wiring harness I bought and make sure it was long enough ect. Well I went to plug it into the cam position sensor and it wouldn't go it. Here is my problem.




Am I supposed to swap my old cam position sensor in the new LS2 cover or is this the wrong connector on my harness?

Has anyone had this problem? I checked my old sensor and its the same as the one on my LS2 as well so I'm thinking its the wrong connector on the harness.

Its not designed to plug directly into the cam sensor. It is designed to plug into the short jumper harness that comes with the front cover.

Ok now I realize what happened, I never got the cam extension when I bought my motor only the cover itself so I never knew about it until now. Is there any alternative that I may have aside from buying a new timing cover just so I can get this damn piece? Could I just remove that little plastic tab inside the current sensor and plug right into it? I can't find anyone who just sells that sensor extension piece.

Maybe I'm misunderstanding the problem here, but why don't you just use the connector on your LS1 harness? I have an LS2 with that same cam sensor connector on the front cover, and I have the MSD 6010 box which is basically made for an LS1, so it has the LS1 connector for the cam sensor.
What I did was lengthen the wires by 3Ft by soldering in an extension in each lead and using heat shrink on the joints and REVERSING the A and C terminals at the sensor. Plugs right in and works perfect. The conversion harness that's sold just reverses these two wires...the center ground wire stays the same. Hope this helps, Ron

I bought the harness instead of extending it myself, unfortunatly I didn't realize that the stock cam sensor has a small harness coming out of it and this is where the Katech unit plugs in.
