We got our '77' Argosy last October. At the time we did not have the proper wiring in our TV. A tech jury rigged a 4 pin so the trailer would be road legal, and all the lights worked.
In prepping for the TAC Ohio meet, we took our Mountaineer to the shop and had them install a brake controller plus 7-pin wiring. We went to pick up the trailer and found that only one light works, the passenger rear turn signal/brake light. No driver's side lighting, no reverse, no running lights, no applied brake lights.
After doing some reading here, I can only assume that the Argosy still has the original 70's non standard 7pin plug. Am I right in assuming this? If so, how easy would it be to upgrade the Argosy plug to current standards? Or would it be easier to just twiddle with the new plug on the TV to get it to work? Finally, if it isn't the plug, where might I look next?
Hopefully we can get this fixed and make it to Wooster by Friday night
