1986 Ford Bronco Dash/Instrument Light Problem

I have a 1986 Ford Bronco XLT (which I just swapped out the tranny from an AOD to a manual) and my dash lights staying on all the time, even when lights are not on. Using the dimmer for the instrument/dash lights turns them down, but they're still draining my battery overnight. Need to find a detailed wiring diagram that shows the wires at the light switch because the previous owner cut, spliced, and rewired the from the harness to the light switch. All other light functions appear to be correct (headlights, brake, tail, turn, parking)

The dash lights on one side work but not the other on my 1997 ford explorer xlt

There are small replaceable bulbs behind the instrument cluster, they are installed in twist lock sockets usually, you have to pull the instrument panel to change them, #194 is a common dash bulb

Speed sensor issue.

I have A 1995 Bronco XLT that had A problem with harsh shifts and seemed to be running in "limp mode". I have had other trucks and cars with these symptoms and the fix was A new speed sensor.
The bronco had no speed sensor on the tranny like my F-150 (also A 1995) although there was one listed for it at the auto parts store. After many days of messing with this heap I bit the bullet and took it to A transmission shop where they tried rewiring the dash. After spending $350.00 it worked for about 6 months when the symptoms returned. The original tranny shop wanted nothing to do with this boat so I took it to A Ford dealer and found out that the speed sensor is built into the instrument cluster which must be removed and replaced with A rebuilt or A new unit.
A new one was in excess of $1000.00 while rebuilding mine was around $600.00. I opted to rebuild my unit. The total for this came to almost $1500.00 to remove and replace the rebuilt cluster. But at least it now runs right.
Another better idea from Ford! Instead of an external,tranny mounted speed sensor that costs around 35 bucks, and can be replaced by the average shade tree mechanic, lets bury it in the dash and charge more than the truck is worth to repair it! And they wonder why the foreign auto makers are eating there lunch.

Disconnect the neg. battery terminal and let sit for 30 minutes before you remove the computer

Fuse panel and fuse identification-Ranger/Bronco II (clic for zoom)

Power Distribution Box
Located under the hood, inthe engine compartment. It houses the fuses and relays for most of theunder hood components which are not controlled by a dash mounted switch(such as the alternator, fuel pump, ECM, etc.). The fuses and relaysare replaced in the same manner as the fuse panel inside the vehicle.The power distribution box cover is hinged on one end and utilizes aretaining latch on the other. Simply release the latch and lift thecover up to gain access to the fuses and relays.

Good luck (remember rated this help).

Tranny swap

You can swap a AOD trans in but is not a heavy duty unit. The E40D is but all electronc and would be expensive.
