Hi
I'm about to undertake a manual conversion on my tj 3.5l series 2 auto. Auto is stuffed.
It's got cruise and srs.
I have a te 3.0l manual car to tear everything out of.
I'm going to reuse the auto ecu without a piggyback and bypass the neutral/park immob.
And wire the brake light switch from the te into the clutch pedal on the tj for cruise.
Will this work? From what I have read it should. Can anyone shead some light on any issue I may encounter along the way.

Everything should work out fine. You can use the same ECU. Pretty straightforward conversion if you have everything worked out properly and take your time on it.
