4-Wire IAC

[mpgmike]

I have a UAEFI on a Jeep 4.0 liter-based '95 Grand Cherokee (ZJ), but with a high compression 4.6 stroker swap. I got the ignition control working. My next step is to take control of the IAC. It is a 4-wire unit with 1A - 1B, 2A - 2B hardware. I have looked at similar examples, but Tuner Studio greys out any options for the wiring configuration. Another Jeep 4.0 retrofit (scfrontier) used pins A1, A2, A5, and A6 to control the IAC. I tried to replicate his settings in TS, but -- again -- what he chose is greyed out in my version.

I was advised to look at GM examples, but again, what was selected in these uploaded tunes is greyed out in mine. Here is my tune:

Can anybody point me in the right direction??

Messed with it again today. Read through the set-up documentation, and again; "Stepper H-Bridge Hardware" section is greyed out. I just started changing settings from True to False, and what not trying to get it to activate. Nothing worked. This is pretty important, I really need to know why mine doesn't work when apparently everyone else seems to make it work.
