Smelled burning wires and tailights and instrument panel went out. Looked at fuse 10 (Park) and a 25amp fuse was there when it should have been a 15amp. Need to trace wires and locate the burned area to fix. Need wiring info or some areas a burn area might likely may be located. Thanks

At the instrument panel fuse block, check 15A fuse 10 (indicators). In the relay center, check 10A fuse 8 (speedometer).
For "back lights" problem: At the left underhood fuse block, check the 20A HEADLAMP BREAKER. At the instrument panel fuse block, check 15A fuse 6C. Both of these supply power to the lamp control module. If you set the park lamp switch to the on position, the tail part of the tail/stop/turn lamps should light, the separate tail lamps should light, the license lamps should light, and the rear marker lamps should light. If any of these don't light check for burned out lamps, bad sockests, and bad wiring or missing grounds (black wires)
I may have a ford wiring book for escort. $5 plus $2 postage. Let me kno wif interested and I will check for it.
tailights and instrument panel lights are on same circuit. I suspect a fuse. Go to motorcraft.com and see if they have an owner manual with fuses identified.
Check that your tailights/parking lights are working (not the headlights) as this fuse and relay feeds all the instument lights too.... Fuse 15amp TAIL & Tailight Relay
If not then check:
The rheostat (also known as the dimmer switch) may be faulty
as it controls all the illumination of all the backlight bulbs and other dimable switches/indicators.
In general bulbs all together draw a fair amount of current so it is possible that the wiring or ground at the major supply junction feeders has failed but that is a less common problem.
So check the rheostat dimmer wiring area first as all illumination power goes through it.
There is further simple testing we can do with the three wires at the rheostat you can check the entire illumination system.
If you jumper the white/blk to the white/blk all the illumination lights should come on (that means the rheostat is bad).
Or use a voltmeter and measure the green rehostat wire to ground it should be 12volts (if not time to check the fuse, relay and wiring)
If not then finally declare the instrument panel faulty (like burned up circuit board trace).
Note of interest: the rheostat also controls (dims) other switches not associated with the instrument cluster such as the cigarette lighter bulb and hazard switch and radio player and A/C control switch. So if those are dimming but not the instrument panel backlights then yes the instrument cluster needs fixing or a very close wiring inspection.
I am currently working on my 92 Deville with the same problem. I was driving along, and smelled what I felt was a smoking printed circuit board. I looked down, and the digital fuel data center and climate control panel were dark.
I have the factory shop manual, and with the aid of a meter and the manual, I traced the problem to a bad BCM. The 16v supply coming from the BCM was gone. Opened up the BCM and found an overheated transistor. I also removed the fuel data center and the Climate control panel. The fuel data center panel did not smell good. I found a shorted capacitor on the Fuel data center circuit board. I am replacing the capacitor, and will be picking up a used BCM at the boneyard tomorrow. I might also have an overheated wire in a cable that might have to be replaced. I have not gotten that far in the troubleshooting yet.
