ON top of everything else going on, I went to the doctor on Thursday & I've ended up with a broken foot, UGH! But back to the Beast.
I redid my harness for standalone using information on a tbi swap from a thread on the board here by cjracing15. After following it to the letter, I still forgot to unpin the AC call wire. Or at least I think that's what it is. I haven't had time to pull the harness loose from the ECM & double check, but 99% sure it's the AC call wire to tell the ECM to increase idle when you turn on the AC.
