I replaced my horns recently. When I bought the truck last December, it only had one in the first place, so I picked up two brand new ones from LMC. The original OE horns had only one terminal to hook the wire to. The new ones have two - so I assumed one was hot and the other a ground. No problem. Now, every time I try to actually use them, the fuse blows. This also affects the cig lighter, which I use to plug my phone into. Right now, I have the horns disconnected since having access to power for the phone is more important that using the horns. Anyone have any ideas as to what's causing the fuse to blow? Thanks !
