I need to change a 1987 wiring harness to a 1984 V4 engine in a Pontiac Fiero.
you can buy a manual at a parts store or you can try the parts stores online. Auto zone O'Reillys and NAPA all have wiring diagrams online for some vehicles. You can also buy a download from OKorder for your car. They are $10 or less usually. Good luck.
