I have a 1998 starcraft starblazer,it has a 4-way plug 1white,1green,1 large black and 1 small black wire.I would like to make a pigtail useing a 7 prong plug.I don,t no where the small black wire goes
I Have a 96 Scamper that I replaced my plug on. The first thing I did was identify all the plug pins, then match the light functions: running lights, turn signals, back-up, 12 volt charging, brake, and ground(7pins). I did not go by color. Most trucks plugs are the same for the round 7 pin. the wiring is usually on the plug cover, or owners manual. Use a little dab of dielectric grease on the plugs for a good connection. good luck!
Hi. What you want to do is just cut the four way off. Then identify with a test light what color wires are truly what, Then just go get yourself a new 7way and with it will be a good diagram on where to connect and run all your wires even directions to hard wire your brake controller and 12v power wire...good luck!
