i have an 93 dx hatch with an obd2 motor

i have put an obd1 ls motor in and used the same wiring harness, just used the obd2 ls distributor....obd2 motor blew so i replaced it with an obd1

now...i'm going to get an obd1 gsr motor, so can i use the same wiring harness if i
get an obd2 gsr distributor? then i will just have to add the vtec wires?
