has anybody used a 99 si harness to put a 2000 gsr into a 1996 civic cx???

 

I'm sure it's been done, but definitely a pain in the *** to rewire considering that the 99 Si harness is OBD2B and won't match up in an OBD2 (96-98) Civic chassis. If you want a harness that is almost completely plug and play, get a 96-98 EX manual harness.
