what all do i need? i know the sensors are different, but are all the sensors different? is it just some of the connectors that make them different? ECU still the same? i got the 99 ECU and engine harness, but no sensors off the stock block. what will i be needing to do to make the YJ 2.5 work in my TJ?
What year YJ? The only thing that I've ever heard of is the water pump on one of the years/or models is reverse rotation of all the other 2.5's. But you'll be fine going from a YJ to a TJ. It's the same engine but adds a few more sensors, nothing major changed and I think you'll be able to start it with the 99ECU and harness.
