SN95 94-95 Microsquirt Pinouts

beyondEOD · Apr 12, 2020

Does anyone have the Pinouts for the Microsquirt to 94-95 SN95 EEC Harness?

It would greatly help me figure out how they are interfacing and working with/around the CCRM. (Specifically the AC WOT Cut and AC Control Circuit)

Thanks, would you happen to have the PNP harness pinouts to the EEC?

Im pretty sure the Microsquirt has nothing to do with the A/C.....ie ,no WOT cutout etc

The diagram you posted is the generic Micro wiring diagram. I'm looking for the exact MS Pin X = EEC Harness pin X for the SN95. The factory EEC is in charge of WAC and ACCS, so I'd be real supprised if they would put out a product that would completely eliminate these EEC functions.

I've spoken with EFI Source about the A/C Idle up function in tuner studio....The Microsquirt module has no provisions for this function, nor does it do anything else with the A/C

Alright that is suprising. Thank you

Well it does, you just have to wire it up so it will work. Pin 10 has the needed input signal 12v+ use the nitrous input for this. Then use any general purpose output to control the wot relay, swap pins 87 and 87a at the relay so the ECU has full control of the compressor.
And your done. If you dont want to move pins it takes an ms3 and a loop function.

Easy peasy
