Does anyone know how to wire my horn to my car alarm. I have an Excalibur alarm system that is suppose to be hooked up to my horn also, but the option does not work. The company that installed it is no longer in business. I have a 1997 Ford F150 XLT. Can anybody help?

i believe the pink wire is horn output for excalibur alarms and you need to hook this up to the blue wire on the 4 or 5 pin plug just to the right of the steering column. this wire will test 12v at rest and go to ground when you press the horn.
