I ahve a 91 CRX with a D16A2 engine, but i didnt come with it. Came with a D15B2... Blew it up. Anyway, I cant hook up the engine harness to the car harness without gutting the entire car ripping out the old harness, finding a CRX that came with the motor and replacing the ENTIRE car harness. **** me. How else can I get this motor running, splice the wires?
