I was working on the white big red and was thinking of adapting the front accessory plug to a modern cogarette or usb plug. Then I thought it might be better in the tool box. Once I started looking at that I noticed my right side tail light plug looks like it has plugs for 4 wires ( pic attached). Wired some plugs on a usb cigarette lighter combo and it worked. Any thoughts. Good bod idea? Pics attached.
