Yea, it seemed easy, but for some reason, I must be screwing something up!
I didn't unplug the battery or the red wire before or during installation (I did when putting everything back to orig as I found it lots easier to maneuver), but I DID lock the doors, and put the fob in the house and made sure the ECU was "asleep" before I started.
Could I possibly be running into issues because I didn't take the hot wire off the battery or unplug the red wire from the ECU? If so, what's the best method or should I do both?
I really appreciate you guys for taking the time to help.
