Got it done today. I want to thank everyone for nudging me in the right direction. Definitely wasn't trying to screw that one up. No more stalling when the engine comes up to temp, and I let it run for 2 hours before taking it out for a test drive.
I wasn't expecting to lose all my hours in the hour meter, it got reset to 0. I luckily took a picture before replacing the ECM so that shouldn't be too hard of a fix.
Anybody know how the life expectancy of the RX ecm's compare to the new one that truck was built with?
