a couple of questions L96 is the subject
When deleting the vvt why does the LS2 timing cover have to be used?
My msd 6012 cam sensor plug does not fit the connector at the sensor. If I was to cut the keyway tab from the connector I could make it work but am not sure if the wire orientation would be correct

Does your LS2 cover have the short extension piece on it like this? It sounds like you're trying to plug your 6012 harness directly into the sensor itself. My LS2 cover came set up as you see it below.
The whole reason for running this cover when deleting VVT on a Gen IV motor is because there is no provision or a cam position sensor at the back of the block like the Gen III motors. Did you pick up a 3-bolt 4x reluctor cam sprocket as well?

I thought about your questions a little bit more and I'm thinking maybe you're asking why you can't just reuse the original VVT cover after deleting the VVT cam and phaser. Its because the cam position sensor on the VVT cover is spaced out to clear the VVT phaser. The VVT motors get their cam position signal from the phaser instead of a typical cam sprocket. Here is a pic each. You can see the phaser is much thicker than the standard sprocket and therefore needs a "bulge" in the VVT cover to clear it. This "bulge" would keep the cam position sensor too far away from the cam sprocket reluctor once the VVT phaser is gone.
Here's a profile shot of my motor with the VVT cover still in place. You can see how far out the cam position sensor is.
I hope that makes sense. I can't think of a better way to explain it right now.

On the msd deal, my gen 4 timing cover had a bracket much like yours with the cam sensor and another plug. These both run to a main plug that would connect to the oem harness. I assumed when I got the LS2 cover to delete the vvt I could use my cam sensor in that cover. The plug from the msd does not fit the sensor. Don't have my camera here, a picture would be best

The LS2 cover, if bought new under part number
12633906, should come with the sensor and extension piece just like the one I showed a pic of above. I think the plug on the VVT cover is different because it is also tied into the VVT, so I'm sure there is at least on additional wire. I'm working off of memory here though so I could be wrong about that.
