New to avic411.com and looking hopefully for the answers to my questions. I am currently finishing the re-install of my 5200 NEX in my 05 RAM 1500. When it was initially installed the speed signal input and reverse gear signal inputs were never connected. Can anyone tell me where to connect these wires on my RAM? Is the reverse gear input just looking for a voltage signal (i.e. reverse lights)? That one I can probably figure out but the Speed signal has me stumped. Can anyone out there help me?
