1988 Jeep Wagoneer Ltd 4.0 mileage: 145,000. I installed a trailer hitch and have a problem with wiring a three pole connector. The three types I tried so far with no luck. Latest is a plug-in type for an 1988 Comanche. Taillights are different. My Jeep has 3 -2 pole lights each side and no matter how I wire in the adaptor, can not get trailer to use two poles. I.E. Turn signals and taillights work but no brake lights, or lights dim when engaging brake. There are four wires in main bundle to the ear with brake signals, have tried all four. Help!

Make sure there is insufficient ground from the Jeep to the trailer lights. Run a ground wire from the frame of the Jeep to the housing for the lights on the trailer.
