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

Check your Tailight fuse to see if it's blown, if so then start checking for a bad bulb(shorted element) in tailight circuit boards . and also don't forget to check grounds as well, there should be one at rear frame by left (drivers Side) tailight connection/trailer harness connection. hope this helps. do your Brake lights Work ?
Have you checked to see if the fuse is blown? The brake lights have to work to get the truk out of park as thepower from the switch opens the gate in the steering colum to let the shifter into gear.the brake light fuse is in the underdash fuse panel. while checking fuses check them all as some circuits effect others so any blown fuse can cause this problem eventhe fuse panel under the hood. The tailight circuit boards are well known to fail and cause blown fuses so unplug the tailights at the light change the fuse and try to ge it out of park If it works plug one at a time the tailights in and you'll find your problem the circuit boards are a common problem so they can be aquired at most parts stores.
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.
Check fuses next, best done with a meter or a test light. You have a panel to the right of the center console in the front where the passengers left foot is, There is also one under the hood by the left headlight area. Remember that fuses for lights are only powered with the light switch on.
You may want to check the wiring under/inside the dash. The AC may have blown the scent of burning wires or other components from the dash. THere may be copper wires that have been exposed or have shorted one another. Then check on the fuse once all wires have been checked out.
There is a n instrument panel fuse and a tail light fuse. Check both with a 12V test llight not just visually. Sound like one of the are blown, probably the brake/stop light fuse. Usually the dash will darken, when a tailight fuse blows, sort of a sneaky way of letting you know theres something wrong. Now is going to be WHY DID IT BLOW ? Hope this helps
