Does anyone know where I can find out fusebox removal...

[rogus]

I'm trying to find out how to remove the fusebox on a 87 Elky. What are the wires on the firewall side? I believe there is a left and right section of the firewall fusebox that comes of independently of each other?
Also trying to identify what connectors are plugged into it.

I can't speak to which connectors do what but In order to remove those wires there's a bolt in the center of that wire cluster on the firewall side. It may be hidden by some Factory installed sealer that they used to weather proof it. Pull that bolt out it's longer than you would think and that will allow you to remove unplug it connector from the engine side. As far as removing the fuse box on the interior if you look at it you'll see 2 fasteners,one and either corner staring directly at you. remove those and the box will come off.

The fuse box has two parts on the outside. They are two plastic tabs that hold them together. They is a bolt that bolts the two outside and inside together.

In terms of the wiring layout, they differ by what year and engine are installed. You have a couple of options to figure out what each wire’s function is : buy a factory service manual - I did this for my son’s ‘80 Cutlass and the pinout was spot on; or you can old school the pinout with a multimeter.

As melloelky mentioned - there are two sides of the engine bay connector - the side closest to the fender is for all of the forward lighting and perhaps horn (IIRC), and the inside plug is for engine.

Both sides of the plug have a distinctive heavy gauge red wire that terminates at the starter hot post. The purple heavy gauge wire is the ignition wire that powers the coil and is hot in crank and run.

FWIW, I utilize the heavy gauge wires in that plug and source the power from an aftermarket post installed directly from the battery. This way the factory in dash fuse panel is operative. I’m f you lan to do away with any of the factory dash, then eliminate the entire mess. But if you want the factory column, lights, T/S, etc, to work, then keep it.

Thank you. Supposedly the car is an 81. It was modified and I thought it was wired like an 86. However recently was able to determine that the wiring is from an 87/88 due to finally finding where the flashers were located under the dash instead of on the fusebox itself. This wiring is a mess.

Sometimes it’s almost worth starting all over again from scratch. Try and correct it. Good luck!
