No the 1988 underwent a big upgrade
To install a 3800 supercharged engine in a Pontiac Fiero, you'll need to start by preparing the Fiero's engine bay and ensuring the engine mounts are compatible. You'll typically use an adapter plate to fit the engine, along with custom mounts. It's important to modify the wiring harness and install a compatible transmission, usually from a 4T65E or similar, to handle the power. Finally, you'll need to address cooling, exhaust, and fuel system upgrades to support the supercharged engine's performance.

Yes It would be esiest if yu has a 1985 V6 Fiero car to get parts off This will require a replacement computer and a bunch of custom wiring and shifter work to get running otherwise. Good Luck

Disconnect the battery. There is no stored memory beyond that.
To remove the hazard switch from an '86 Fiero, first disconnect the negative battery cable to ensure safety. Then, remove the trim panel surrounding the switch by unscrewing any fasteners and gently prying it off. Once the panel is removed, locate the hazard switch, disconnect the wiring harness, and unscrew the switch from its mounting. Finally, pull the switch out and replace or repair as needed.
For a wiring schematic of a 1985 Pontiac Fiero, it's best to refer to a repair manual specific to that model, as it will provide detailed diagrams for various systems, including electrical, ignition, and lighting. You can find these manuals at auto parts stores, online retailers, or libraries. Additionally, automotive forums or Fiero-specific communities may have shared resources or scanned copies of wiring diagrams. Always ensure to cross-reference any information you find to match your vehicle's specific configuration.
the only thing you can do is track back your wires where they are fried and try to fix them or worst case you might have to replace the wiring harness itself. good luck
