I recently bought a 2006 GW with Motor Trike body. For some reason MT did not put a pig tail plug for a trailer. They did however put on a hitch receiver. Now I want to put a pigtail on this thing but I am not sure were the plug in wires are or what they look like. Can you guys help me out? Oh, by the way what plug and play should I get? I appreciate any and all assistance.
