5013, RE: Can't get crank signal ms2/extra

I would try hooking the signal wire back up the stock ECU to see if anything changes. It’s possible the ECU is bringing up the voltage; it’s been a while since I looked into it. Looks like the SBECIII and the FCC use different pull up methods?, i could be wrong though. All the CPS’s I’ve used for my crank/cam projects either outputted a 5v pulse or a smaller. As I’ve said before if you can swap the two outer pins and see if it changes anything.
There always is the chance of damage by wiring it up wrong.
