I have 2012 Ram 1500 Express. I just bought a Varad LED Scanner model # VS350BL-EVO to keep the scumbags away. The instructions say to wire it per the following
Red Lead = to battery (constant)
Black Lead = battery negative or chassis Ground
Orange = Ingnition
Has anybody installed one of these, I can't find a good spot to route the wire through my firewall to the battery/fuse box?
