1988 MJ Horn Problems

Alright guys, I have been trying to diagnose this horn problem and I can't find a clear solution. I desperately need to get my truck inspected (EXP 6/12) and the last thing on the Texas DPS list that I need is a working horn.

So I've disconnected the horn button panel from the wheel and there are two wires. One running from the column to the button and one running from the button to nowhere. I know that the second slides into a hole on the column but still does not activate the horn while the truck is running. I've looked under the front bumper, drivers side and cannot find the horn. I'm lost and this is my only day off.. I need HELP!!!

Horn:



Under the front bumper:



So as far as I can see the only thing under the front bumper is the front left turn signal. There is nothing below it, not the horn or anything for that matter.

Please, any help would be much obliged!!

Thanks,
Brett

Not much info here.
Look everywhere. Do you have a horn or not?

Ok so I got it to where when I push the horn button I can hear the horn relay clicking in the fuse box which is good news. So at least I have current running through the wires. I then looked under both sides of the front bumper and found a wire on each side leading to nothing, with one having a plug on it. I'm assuming this to mean that the PO took both the horns off and now I get to replace them .
