You might got lucky both circuits should have protection for short to battery.
Still never worked though from the beginning. I just ordered a spare Pcm from ebay . Kinda makes me mad to get it towed here where I have everything its like $120 and its less than half a mile from the tow service to the car and back to my house. No clue, I did what I was supposed to do with it in the car and would not read. I would be much farther ahead to build the trans and ls swap it. Thats more money though.
