Help on hooking up Piggyback/ e.c.u. pin out

[Koenigturbo]

I'm hooking up a A.F.R. piggyback. What I need to know is this: Which pin out on E.C.U is the power ground for the piggyback. The e.c.u. has two terminals for ground, one is a logic ground and one is power ground. Which one is power ground? eo1 or eo2? I think it's eo2.

Second: On the E.C.U pin out: which terminal sends the R.P.M. signal to the piggyback? Is it the tach or is it the C.P.S.? What's number or letter would it be on the pin out?

We have a piggyback section for answer those types of questions. The which wire goes where questions.

After further review, maybe that doesn't answer your question.
