I just bought 97 gt manual 4.6l . Seems there’s been things done to it . What? I don’t know . It’s quick and it’s fast. It has msd ign but seems to be bypassed. A bunch of wiring for the coils just laying there. I have no idea why or even where the msd brain is. I assume that’s where the bypass plug is
