Let me do some digging on what the switch panel and horn entails. The P1K horn I belive had it's own button for placement near the steering wheel. The Talon may be different, I haven't had time to look at much of the accessories. Everyone we've sold so far has left with their stuff still in boxes or with none at all.
Again, I/we all appreciate your input on this forum and thank you for posting installation instructions as I used most of them. If I come across as frustrated, I am. But certainly not at you or anyone on this forum.
