After what I thought was due diligence searching the forums about trailer wiring and talking with Curt Hitch Company I installed a non-powered converter box to my lights. I did not short out while plugging the wires into the back of my tail light connections and all checked out well. Drove to U-haul with no problems and plugged into a trailer for a test, all lights on the trailer worked correctly. I unplugged and drove away then the glow plug warning light started flashing, power windows won't work, keyless entry quit,sunroof quit and tailgate won't open. All lights work, fuel door and cruise control work. No bad fuses, fuse links on top of battery good, trailer wiring has been removed. 02 Golf GLS. Anyone know what the fix might be.
