    M60 Wiring Assistance needed

    After over a week of running through the ETM's and comparing various other swap guides, I've gotten this far but need help in completion.

    My car is a 05/85 325e, which had the square c101. I stroker-swapped the engine previously and had to convert the square to a round C101 from an 87 325i.

    Wire colors are noted from body side on the e30, going to pins in the round c101. X20 harness is from a 94 530i/5 and wire colors are noted as engine side.

    Do all the wires combo's look correct to you guys?

    The one's I question are lines 31, 32, 35 and 36 as noted in the excel sheet below.

    I'm not sure what line 31 connects to in the x20 harness, and I think line 32 is the correct connection?

    Are the functions for 35 and 36 being connected from x20 to c104? If so, what wire/pin are they connecting to on the x20?

    My C101 pin 6 is wired to X20 pin 22 for the O2 Sensor relay. C101 pin 11 to X20 pin 19 for the "SI Reset". I have my X20 pin 17 wired to C101 pin 16, but I haven't hooked up a code reader to the diagnostic port to see if it's working correctly.

    My fuel rate output is C101 pin 8 to X20 pin 24.

    Here's my adapter map, I got my engine up and running with this adapter this week but like I said, I haven't tested the diagnostic connector.
