The two big post on the ford solenoid carry the load & amps. The smaller two connections are what trigger it. A relay is not required.

#1- Battery + to 1 big connector of FS.
#2- The other big connector of FS to siren.
#3- ground siren to truck make sure you have it good and cleaned.
#4- If using the truck horn button and relay should be green wire ran to FS small connection. Then the other small connection to ground. The siren should work when you push the horn button.
