Hoping for some definitive info on throttle bodies. My 6.OL project is running a gen 3 PCM, throttle body, harness and tac module from a 2003 Yukon. I'm using one of the aluminum adapters to go from the 3 bolt throttle body to the 4 bolt LS3 intake manifold. I saw a picture of a 4 bolt throttle body from a LY6 that looks like the connector is the same as my 3 bolt. Anyone know if they are compatible electrically? I'd like to do away with the adapter if possible.

Thanks!
