i have a 90 std hatch. I recently put in a 90-91 Si hatch front body harness in it. I put the 90 Crx Si dash with the Crx Si dash harness, and the dash harness plug wont plug into the plug above the fuse block..The connector is the same size and looks to be the same amount of pins but the grooves dont line up???? Anyone know if i could just trim the grooves out and will it work or do I did to run a Si hatch dash harness with the SI body/fuse block harness????? or vice versa...
