obviously the engine management harness is different between the two models, but is the body harness and the harness connecting to the alternator, starter, and battery all the same? can they plug right in to each other without a problem? im finding that some of the wires dont match up ANYWHERE so i just wanna make sure im not seeing things.

 

just to add some clarity, there's a seperate harness that detaches from the body harness coming through the firewall on the driver's side. that harness is connected to the engine bay fuse box and battery cables. can you swap that harness between the two cars?
