different question but the same topic....if i'm using the dominator but plan on using the 4500 style TB will any TB plug into the harness or 1) use the holley TB or 2)repin the plug to use on a different TB...
I guess people skipped my reply previously, and I wanted to clear this up. Can a LS1 harness be used on a LS2 engine - Yes with modification.
There are more main harness's submitted for production. However for the LS based engines, there are two configurations made. The LS1, and the LS2. I know you are trying to assist, however the harness's do have different part numbers for reasons that go beyond wiring lengths, and connectors.
The LS1 crank sensor connector is pinned back to EST 12V output on the P1B connector.
The LS2 harness has a 5V ref voltage and pinned back to P1A connector. Long story short here. USE THE APPROPRIATE HARNESS for the engine. It's not just a programming difference. Thanks -Derek

If you are running a LS specific harness, the connector should have the same style ( 3 wire small round) connector as the 4500 TB TPS sensor. The IAC connection will be different

If you have the schematic for both harnesses you could add the provision for both the 24 and the 58 tooth. There is also a signal converter to run either with a stock PCM. Not sure if that would work with the Holley unit.
