[RC] Trailer wiring - k s swigartMike Maul said: I'm looking for the wiring diagram for the cable of an older - 80's - horse trailer made by Ponderosa Trailers of Conway, Arkansas and Delta, Co. They are a Div of Central Arkansas Fac. I'm told that it does not match today's standard for connectors to the truck. It likely doesn't match the original wiring diagram either. What you need is a test light and somebody at the back of the trailer telling you if/whether any lights go on and off (my dad and I did this with my old Stedham at the end of the second day of the Outlaw Trail and provided a great deal of amusement to everybody else who had ever worked on anything with their dad). Barring that, you can take it to a trailer hitch/wiring shop and pay them to do it for you. Make an appointment and they can have it done in an afternoon. If it DOES match the original wiring, then you can take the connector off of the wiring harness on the trailer, and on the back side of it there are usually letters next to the pin holes that say, RT (right turn signal) LT, (left turn signal), TM (trailer markers, i.e. running lights), GD (ground), and S (brakes...or auxiliary...NOT brake lights, to get brake lights the truck should just send a charge to both the RT and the LT wires; and a post up the middle, which doesn't have any letter by it. My 1973 Stedham had the same wiring pattern as my 2002 Exiss does...as did the '68 Miley, and does my '93 Logan. If your trailer doesn't have the standard 6-pin horse trailer wiring pattern, it is probably because somebody has monkeyed around with it since it came from the factory (probably somebody like me and my dad in Esclante where we were unconcerned about factory settings and just wanted the wiring on the trailer to match the wiring on the truck...and we stopped monkeying around with it when it worked...for that day :) since I spent time monkeying around with the wiring on that trailer until the day I stopped using it). Which leads me to my final suggestion. If you ARE having problems with the wiring for such and old trailer, _I_ would suggest taking it in and having the thing professionally rewired--which is what Pat & Dwight did last year with their '85 S&H because they got tired of monkeying around with the wiring (actually it is what Patty did for them when she borrowed it from them and realized that the wiring was less than reliable). When it comes to old wiring, usually the best thing to do is to pull it all out and start over from scratch. kat Orange County, Calif. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Ridecamp is a service of Endurance Net, http://www.endurance.net.
