buy an obd0 to obd1 ecu jumper harness. if anything messes up later then you can still convert back to obd0.

This is Only true for some of the pins. Obd0 plugs have bigger pins on 1 connector where as the obd1 ecu uses about 5-8 pins that are big than the rest of the plugs. So the OP will still need to do some splicing/soldering.

I could be wrong on the number of bigger pins, just going off the top of my head.
