The wires arent labled? Most conversion harnesses are different. Follow the directions

Contact who you purchased it from and ask them.

Do this...

But if you know the color, just hook it up accordingly. I dont understand your situation I guess.

Although I didn't use a "conversion harness" when I did my converstion from OBD0 to OBD1, I think I know what is causing your confusion.

The conversion loom section that goes between your OBD0 chassis loom and OBD1 computer has several wires that are "loose" due to the fact that those circuits are not part of the OBD0 chassis loom. They have to be wired directly to the component.

all you need is the wiring diagram for a p72 or whatever ecu you are running. Are you a dx or si, cause you'll have to do dx to si conversion first. I've put two H22's in 4th gens already and wired them up perfect. Distributor is the most important to get perfect, the rest is easy.
