Your soldering (and desoldering!) skills are apparently better than mine!
I just ordered the GP3 switcher package with the larger 32 pin chip and ZIF (I already have the remote switcher from my 7747 ECM) and the header to read the stock chip. I know, I don't really need the header, but since I have two stock chips, I'd like to see what they have on them.
1987 Grand Wagoneer, slightly longer than stock.
Don't mess with me. I once killed a living hinge.
