99-00 civic si engine harness into 99-00 civic ex
hey i have a question about using a 99-00 civic si harness in a 99-00 ex. the ex harness has 4 plugs and the si harness only has 3 for the ecu? someone told me that the 4th plug is integrated into the firewall or something. im lost on this situation. if you could help me clear things up and tell me what i need to do to use the si harness in this car with a b16a2 or if it is even possible. thank you for your knowledge and time!
