I had an 8350, 6AL and tach adapter and I shorted a wrench on the back of the alternator.
the car would barely run (roughly and wouldn't rev). I removed the 6AL/adapter and tried to run the car with the 8350 alone. It wouldn't start/run. I checked the wiring 20 times.
I replaced the tach adapter and it ran fine.
Just fyi
