1988 Pontiac Fiero
Crutchfield Customer Review (What's this?)
This is a perfect fit to plug into the fiero wiring harness with out cutting up the fire harness. However, wire colors do not match, so you have to match the correct new radio speaker outputs to this harness speaker output wires. Take your time and match the speaker output for speaker out put and everything work as expected.
Pros: Works well, no cutting into fiero wiring.
Cons: 25 year old wire colors are not the same as todays standard. Not a big deal, you just have to take your time and match them up. Crutchfield does provide a color wiring diagram. Just match it up with the new radio diagram and everything will work well.
