Gauge problems

[KiltedBanshees93GT]

Thanks Jeff, the tips on the physical removal of the harness will be priceless, that was one of the things I was dreading.
And yes, it is for the '66, my '93 may be a lost cause w/o a garage to work in.
I've already got most of the supplies except the soldering gun, but we carry those at work for cheap.
I've also for the Ford wiring diagram for the car.

One of the wires was blue, I think it may be the rally pac clock power, but I didnt dig that far in. the other was I believe blue/w black, ending in an "o"ring. There were also a couple of foreign wires, run into the light switch and the harness bundle.

I'm leaning toward removing the whole thing, given the extent of damage (thats what I get for buying w/ my heart ).
As it stands right now, this is what is not working:
gauges (the lights do work now tho, and the speedo and tach always worked)
Radio (aftermarket pony style)
Door light switches (one is completly missing)
Lighter
Hood and trunk lights
Fog lights.

It has an aftermarket blade type fuse box, no idea how its wired. Its enough to make me think about getting a Painless harness, but @500 a pop, thats not really feasable right now.

Anyhow, thanks for the help, I'm going to save your instructions in word for later.
