Wire removal for dash removal
Dash is dangling and ready to come out, but I can't figure out how to get the wires out the way on the drivers side so it will be removed. I thought this was going to be a piece of cake, turning out to be one of the biggest pain in the *** things I have done on this car. My searches haven't been able to help me.
Please assist me fellow thirdgenners! thanks!

Re: Wire removal for dash removal
That's because the wiring is SUPPOSED TO come out with the dash. That's how the factory put it together. If you do it that way, it's a total piece o cake.
Locate the bulkhead connector; down by the driver's left foot, about 4 - 5" square with about a million wires in it. Go locat the other side of it under the hood. In the center of that, there will be a small screw; 7 or 8mm head if memory serves. Loosen that screw and unplug the 2 plugs that plug into it (one goes to the engine, the other goes to the body, for headlights and turn signals and such). Now get back into the car, and unclip the fuse block that sits on top of that connector (has 2 barbed legs that just sort of grab onto it if I recall correctly). Now remove the 2 screws that hold the bulkhead connector itself to the firewall.
Now remove the dash with the ENTIRE wiring harness, INTACT, still attached to it. You will have to unplug certain things along the way: the ignition switch (2 plugs), the dimmer switch, the Fisher Body plug, the plugs to the radio, the ECM, and the AC ctrl head; and maybe one or 2 others depending on what options your car has.
As said, total piece o cake, and VERY easy to put back, since as said, that's how the car was built in the first place.

Re: Wire removal for dash removal
I don't know about the fuse block clipping over the bulkhead connector,
since my Formula isn't configured that way. But sofa is spot-on about
the bulk-head connector, and then the collection of secondary connections.
Good luck.
