you could just tap in wires and splice, but thats a lot of work.....
swapping in a whole harness would be easier.... im willing to bet the harness is probably identical and its jsut the computer that needs swapping....
be careful though, smog techs are getting mroe and more anal these days, and some will tag you for anything.....
Maybe where youre from. Up here they dont look at the harness and computer to see if its correct....
