I'm looking into a 93 rx7. the motor blew at around 90k and he replaced it with a 99 jdm motor. the problem is sinces there was a computer change over not all the connectors work and he can't find a 99 jdm wiring harness. he has both the us and jdm ecu and bought a brand new us engine bay wiring harness to go with the sale but i need to know if this is a fixable prolem or what i should do. any help would be much appreciated.
