wierd horn problems

I have a 1998 F-150 2wd 5.4L reg cab long bed and when i push the horn button a bunch of wierd things happen.

The turn signals blink (kind of like if i had the hazard lights on),the dash lights dim(as if i turned on the headlights), the rest of the interior lights come on, and now the horn doesnt work. is it a relay?

It sounds like you have lost a ground somewhere. Does the horn still work at all?

it worked for a while (even with the other stuff going off too) but recently it stopped working, i checked the fuses to see if i blew the horn fuse, but they looked good havent put a meter on the fuse yet tho.

i forgot to write in the first post that b4 i unhooked the alarm(wasnt working right) it would go off when i hit the horn and the alarm light would blink when i hit the horn also.

I dont know if this has anything to do with it but after like a week from buying the truck i replaced a battery cable end because it was corroding. I dont remember if the horn thing was doing it b4 i replaced the terminal because i just got the truck and didnt use the horn.

make sure the wire from the fender <or radiator supprt was reconnected to the battery ground>

you may have disconnected a ground when you disconnected the alarm

i hooked up the alarm, and it is still doing what it use to, the alarm is my horn. Where would there be a ground i should look for?

Also when i was making sure that the horns were still hooked up, and i found a plug near the horns that i couldnt find the other end of the plug for, could it be a plug for fog lights or something? it had 2 wires going to it. I would give you better details about stuff but im in skool right now.
