wiring for 7 prong trailer plug.
i have a 96 zj that didn't come with a tow pkg. added a 4 wire flat for towing with no problems. tried using a 4 wire to 7 prong adapter, lit the trailer for 20 seconds then the light went out. It also took out my left tail light. However, my tail light came on after a minute like it reset itself. I did not hook up any of the wires for electric brakes, could that be a problem? The ground was temporarily stuck into the 4 wire plug, and i did not hook the black? directly to the battery...other than that generally confused, any suggestions would be appreciated...
