2001 Ford Ranger Alarm Issue

Having problems with my 2001 Ford ranger 3.0L v6, when the alarm goes off or the horn is blown the horn only makes a slight honk sound, the lights flash all other indications seam to work correctly during alarm, just the horn does not sound correctly, I tested the voltage with a DVM, during the horn cycle there seems to only be around 6 VDC at the horn, I am assuming this is why the horn is not sounding correctly, when I connect the horn directly to the Battery the horn sounds correctly, I do not believe that it is a grounding issue at the horn. I cannot find a correct wiring diagram and what I think I have been able to find is that the horn voltage comes directly from the Alarm module? Is this correct? Any advice?

There may be a relay for the horn that isn't making good contact when it works. Some of the other relays in the truck are the same as the horn relay. Try swapping it to see if that makes a difference.
