So I added a kill switch, re routed the two switches and activation button so they are now in the gun box. I was actually surprised as to how easy it was to do.
The rest of the customization will have to wait until spring. I plan to repaint it, add a vent light and replace the front hand grip so it resembles the Spengler wand and add the proper cables. Not sure about the light bar yet as I don't know if there's enough space inside.
If someone is wondering why I didn't just use a Spengler wand I consider that a collector's item and I don't want to damage the one I have.
