Anybody know the schematic? I think A is signal, B is ground, and C is switched power.

Anybody know for sure?

On an LS2 A is signal, B is low reference (ground I believe), and C is reference voltage.

Jody,
Excellent, thanks! I think we agree.

A == Signal
B == ground = low reference
C == switched power = reference voltage = ignition = 12V

Do you know if that is the same as an LS1?

I'm getting my 950 Commander and eDIST acquainted ... hopefully love will blossom and they will live happily ever after.

Or it could be very ugly. :)

I would guess they're the same, but I'm not sure. I do know that with the EFI systems I've used LS1/2 are the same systems and have plug-ins for crank and cam, so that tells me they're the same.

Good luck John.

Sounds right, and thanks.

I've got the harnesses wired up in prototype fashion. Time to get this sucker running!
