Im having trouble wiring up a fuel pump relay. my issue is the dash harness is a 91 which expects the relay to be under the seat, but the harness that goes from the kick panel to the back of the car is a 92-93,which expects the relay to be in the engine bay. what would be the solution to this? could I just wire in a relay in the 92-93 harness where the 91 would go?
