Can I make a cowl harness from an OBD2 manual, work in my OBD1 auto? I've already taken out my trac pumps, so the missing wires for that wont matter, and I have an aem instead of stock ecu. Also have 98 headlights already(dont know if it matters). I'm not sure what else the cowl harness is connected to that would be different, and am away from home, so I cant look at anything myself. Any help is greatly appreciated.

Mods feel free to delete when I get my answer.


Thanks!
