but then you're saying the connector that connects to the ECU is identical, regardless if it's an automatic or manual engine harness, correct?

So for example if I have an automatic engine (with an automatic engine harness lets say), and if I were to connect a manual ECU it would fit the connector on that harness?

Sorry for asking so many questions. i just need some clarification that's all. Thanx

No, the auto ecu actually controlls shifting, so it's not a connector for a sensor, its a connector for a shift controller. On the manual, the connectors are both sensors, I believe.

Yes, the ecu connector is identical.

Yes, the manual ecu would fit fine with the auto harness, but you wouldn't have the appropriate connectors to plug the auto harness into the manual tranny.
