Diagnosing and fixing obs Ford rke remote keyless entry module part 1

all my lights would randomly come on and the horns would blow constantly until i disconnected the battery. also it wouldn't allow me to program remotes for the keyless entry

I swear you have patience with these cars lol

LOL probably more than most but trust me its much easier to diagnose the old stuff vs the new stuff.

What year truck is this?
I have a '95 and have been wanting to put in the module for the keyless entry.
But I realize that my truck doesn't have those plugs.

I have a 94’ f150 xlt 5.0 V8. I have had issues with fuse #8 popping. Ofcourse I tried to replace it first thing, but it continued to pop. I’ve since then been trying to diagnose the cause of the issue.
The closest thing I’ve gotten to so far is when ever I unplug the keyless entry the fuse doesn’t pop and speedometer/odometer and door chime come back on. However, I am still without dome lights, courtesy lights, powered door locks, and powered side view mirror adjusters.
I removed the module and opened it up. Doesn’t seem to be fried to me, the panels look mint. There is some corrosion on the the pins that the wiring harness connect to.
Have no problem buying a new module off of eBay but I am hesitant because I’m not sure the module is the issue now that I have opened it up and looked inside.
Curious if you had any input? Thankyou for your time.

Do you know what's on that fuses circuit?

[@killiandoussan6896]

Fuse #8, 15 amp. Responsible for:
•courtesy/dome/cargo lamps
•electric outside mirrors
•radio/clock memory
•speedometer
•sun visor mirror illumination
•warning buzzer/chime module
Now that the keyless entry has been unplugged, the door chime, speedometer, and odometer have returned. I am still missing all the above listed features. All my fuses are fine.
Most people on forums I have talked with said that without the keyless entry hooked up you cannot have these features. But when hook up the keyless entry I lose everything because the fuse blows.
Fuse #12 , 20C.B.
The fuse responsible for power to the module and the power door locks (which you need the remote entry module connected to be able to use) are fine and receiving power.
Normally I can get around fixing things on my truck but this one has stumped me.
