I wonder if my truck comes with that. Do you have a pic of what you're describing?The Isuzu has a terminal on the driver side of the cab that is fused and always hot. I ran a wire in wire protector from Tyberg cab.
Thats why there are two. There is nothing more profitable and easy than applying protector or deodorant with a cordless sprayer.I had the battery one for years. Great idea, just spray and go. But over the years, wish I had the corded one. I like the no worries about how great the battery is when its time to spray, so I sold my battery one and got a corded one. Love it. Yah you have to find a plug but the less worries, the better my day goes.
Pretty cool, Ron. We do something very similar, but only 1 per truck.
