yo,
This problem could be caused by a # of thangs as you know;
get it scanned for Free this at a local parts store,
make sure they do both Key On Engine Off (KOEO) & Key On Engine Running (KOER).
, no matter what they calim, which is usually, "it doesn't matter", bu *** does matter.
There are two types of ODB II Tests, Key On Engine Off (KOEO) & Key On Engine Running (KOER).
The engine temperature must be greater than 50°F (10°C) to pass the KOEO Self-Test
and greater than 180°F (82°C) to pass the KOER Self-Test.
Run it around to heat the engine up and shift thru all gears incl Reverse. Then turn off all accessories/lights, etc.
Make sure A/C is off and transmission is in Park (automatic) or in Neutral for a Manual & release clutch.
Do Key On Engine Off (KOEO) portion first.
Look Codes up in my broncolinks.com site using the new Search function.
And Post em here according to KOEO & KOER

Transmission Control Indicator Light (TCIL) Troubleshooting in 92-96; "... Several different complaints concerning the overdrive cancel indicator may occur due to a faulty O/D cancel LED. At times the light may simply fail to light,
flicker erratically, or glow very dim. Tapping the shift **** lightly may affect the operation of the LED, causing it to work temporarily. These complaints are usually due to a faulty O/D indicator LED. To replace the LED carefully pry the cap off the end of the shifter and pull the LED/switch out. Slide the new switch into position and snap the cap back on. Note: Don’t confuse the above conditions with a steady flashing pattern of the O/D cancel light. A steady rhythmic flashing pattern indicates a malfunction has been detected by the computer.; Part #F58Z-7G550-A..."

E4OD Overdrive Cancel Light & Switch Replacement; It is easy to replace & under $12.00 from local Ford dealer or
OUR SPONSOR; Jeff's Bronco Graveyard;
"This is the overdrive button on the end of the column shifter, comes with small cap. Price: $10.00."
be ready to catch the switch/LED assy when prying it off; it is spring loaded..not much force.

Check wiring where shifter meets column and down;

"...check the wires coming out of the shifter handle, I have had several trucks have those wires short out and cause some strange symptoms. Just pull the plastic cover off the top of the column and take a look, it's pretty obvious when it happens..." by jrainw
Here is a TSB that deals with it; for a 92 though.. and may apply, becuse Ford does mention Fuse 17;... even tho year range is off...
