3.2 conversion wiring question, does the pms wiring harness has a red wire for pressure sendor? Options

[buck toenges]

I am having problems tracing the red wire from the oil pressure sender of a 1988 3.2 engine through my 914 so I can hook up my oil pressure gauge. So far I haven't found the wire through the 914 body harness by using a continuity check. I have a pms wiring conversion harness and by looking at the diagram it looks like the oil pressure wire is a red wire on pin location 4 on the 911 side. Can anybody help me locate the proper wire for the oil pressure gauge? Is it indeed red and does this wire run from the pms harness through to the dme harness and change color?

Thanks,
Buck

I would like some feed back on what I have found so far:

This is using 1971 914 wiring harness

the switch on the driver side on top of the engine by the transmission which I assume is the "idiot" light for oil pressure is number 9 pin on the 911 engine harness plug. There is no corresponding number on the pms harness. I will have to add a wire and run it up to the gauge. Since I am not using the heater blower pin I think I will put that on the pms harness at pin 9 and use this for the idiot light.

the number 4 pin on the 911 harness ends up on the 914 engine harness at t5 which is a green/blk stripe. I have traced this up to the gauge area but can't find an end to test for continuity. Can somebody tell me where the green/blk stripe wire is suppose to end up in the dash?

The number 3 pin on the 911 engine harness ends up on the 914 engine harness on pin number t6 which is a green/red stripe. This is the oil temp sensor that is found next to the oil pressure sensor.
