I built a jumper harness to swap a 2G flashable ECU into my 90 Talon AWD. I know it's not a GVR4, but the wiring should be the same.

I can't find a list of which wires on the OBDII port need to be connected and to where they be connected. Currently, I have OBDII pin 1 attached 2G ECU pin 56 with the yellow wire and OBDII port 7 to 2G ECU pin 62 with the pink wire according to the wiring guide I found.

What else needs to be connected?

The only wires the OBDII port needs from the ecu are power, ground, and K-line. The L-line is not used.
Connect OBD2 Pin 4 to chassis ground - DSM pin 101
and OBD2 pin 16 to switched power - DSM pin 102
