nabera Posted June 21, 2020 Report Share Posted June 21, 2020 I was comparing the pin outs in the MR2Link V1 installation manual with my 1991 FSM Wiring Diagram and I found a few things I was hoping to get clarified. 1. In the MR2Link V1 it shows AUX 6 as A/C Request for PIN 63. This has no connection into the ECU. I believe this is typically for the a PIN labeled "ACT" but the 1991 MR2 Turbo does not have this. I assume I can just leave this as an open AUX for future use? Is there anything else I need to wire as an AUX for the A/C with the Link ECU? 2. I saw this elsewhere but PIN 34 in the MR2Link V1 shows AnVolt4, the FSM has this as the knock sensor. I assume AnVolt 4 is actually for the AFM (which will be deleted anyways). 3. AnTemp 3 is shown at PIN 45 which is the EGR Temp Sensor. If I want to use the GM IAT here I would assume I just wire it to this pin. 4. The Open and Close Solenoid in the MR2Link seems to be reverse from the FSM. AUX 2 which is listed as ISC Open in the MR2Link is wired to PIN 18 which is labeled RSC (ISC Close) in the FSM. And AUX 1 which is ISC Close in MR2Link is wired to PIN 5 which is RSO (ISC Open) in the FSM. If this is in fact reverse, should I swap these or is this configurable in the PC Link software?
