Hi all. I want to wire up a flat 4 plug pig tail for towing a trailer on my 85 Westy. Should I use a powered converter or just use a non powered plug and splice in to the tail/brake turn wires? If I use the powered plug where will the heavy red wire splice to? Anyone have a diagram for hooking up a trailer plug in an 85 ? I probably can figure it out but don't want to butcher the wiring. Any help is appreciated. Thanks.
