94 b18c1 into 91 gs

so i have a 94 gsr motor and im going to put it in my 91 gs. i need an obd0 wire harness cuz my car didnt come with one and i been searching all over for one so i was wondering if i could use a crx 0bd0 wire harness???

Crx harness is for D series motor and you want a B series motor. It wont work. Plus the crx is obd-0 and your motor is obd-1. If you want to do this swap check tegtips for your answer.
