5th Gen HD Ram VSIM | Aux Switches | Wig Wag Headlights

Using the two of the factory options combined to enable the headlight and taillight markers wig wag mode; the aux switches and the Vehicle System Interface Module (VSIM). The VSIM has a ton of features, I'm using the very basic features for now but plan to look deeper into it's abilities as I own the truck.
