You won't find anything that's plug/play with a Fiero chassis. Your best bet is probably a universal harness from a company like Painless, which you would then modify to interface with the Fiero.

I like the method of just getting 90% of the camaro harness, and giving the right bits power and ground, and retaining the ECU to motor connections like they come stock. There will be some of the body connectors from the camaro that you wont use, but its not a huge deal to cut them out.

Cut wires have no place in a functional harness.

There are also chassis connections like tach, back up lights, VSS etc that go through the C500 connector.

You have a harness yet? I have a complete TPI harness here for a friend thats for sale. It is the speed density style harness.

He had it here so I could modify the harness to work in a Fiero, but I easily convinced him not to go L98.....

Just take an L98 sell the TPI and swap on a Holley Stealth Ram... You'll only be out a couple of hundred $ and you'll have 50 more HP. The L98 longblock isn't that bad.

Nope, nothing changed on the harness, it is uncut and complete.

what would you want for the harness. and what would you charge to have it modified?
