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.
