The car (91dx hatch) was bought with a blown motor and electrical issue in the vehicle wiring harness. I swapped a jdm obd1 zc in it. The motor came with no wiring harness, i have enough pieces from other harnesses 90-94. Is it possible to rip the existing chassis harness and fuse box out. Then its place put and after market fuse block with switches to run lights, fans. Then make a custom vehicle harness to wire into a second fuse block then directly to the ecu.
