Ok so I just picked up this truck and it doesn’t have the correct stock steering wheel. So I go to check horn and pull off the cover and see there’s no wire on steering wheel cap. I used my screwdriver to make contact and the horn sounded off once and no more??? I can hear the horn relay click whenever I make contact but no horn. The truck has all new wire harness from engine side firewall out and new horns as well. Could it possibly be the relay it does look original?
