I have a 90 DX hatch, with a GSR swap that I'm trying to finish.

My first time with wiring as well.

car has an allegedly completed DPFI to MPFI conversion, as well as an 0bd0- 0bd1 conversion.

Car has fuel, spark, air, etc,, but wont start.

So I'm trying to trace everything back, but I can't seem to find a Pm5 ecu pinout that has the colours as well.

What I have found hasn't matched up so I'm reaching out here to see if Anyone can assist with clearing the confusion.

So my two points of inspection are obviously, the pin positions of the conversion from obd0-0bd1, as well as the 14 pin plug pinout that goes from the ecu to the engine side harness to connect everything together.

Much appreciated in advance.

So I found a PM5 pinout on another website that I seem to not be allowed to link or it won't work for some reason.

I went over the colors and spots for the wires, and nothing seems to match up. There are wires where there shouldn't be as well.

BUMP, really need some help, I have started cross referencing ****, however cannot find a diagram of the 14 pin obd1 connector that runs from the ecu to the engine harness.

If anyone has a visual diagram of its pinout, it would be greatly appreciated.

^I have that, not what i need to confirm.

I'm trying to confrim the pinout on the connector plug running from the ecu to the engine, and the specific pinouts on the plugs going into the p28.

This plug has 14 pins, and has the injectors, speed sensor, VTEC solenoid etc pinned into it. I want to make sure I have them pinned into the correct locations.
