I'm in the middle of an ls1 intake swap and I'm having some problems with the map sensor. I have the map sensor extension for the ls1, but the connector won't fit on the ls4 map sensor. Did you guys splice the wires or should I be using a ls1 map sensor, thanks.

You have to use the ls4 one look at the Sticky it requires modification

Ls1 and the ls4 use the same map sensor. Something is wrong with your extension harness just pull the wires for the map out of the loom on the cars harness its long enought to reach the rear of the manifold.
