I've looked through a lot of other threads and I haven't found an answer. I have a 1990 hatch that had a d15 obd0 ecu. I just swapped a b18a1 obd1 and some of the wiring isn't lining up. I've gotten it to crank but when it comes the to fuel, the resister box wiring is not the same. The stock wiring that was in my car has a 12 prong plug, while the resister box from the swap has 8. I haven't been able to find any adapters or wiring diagrams to hard wire the 2 together. Just need help getting my car running. Thanks in advanced
