I installed a diode kit so that I can connect my TJ to my motorhome for flat towing. Ever since I did the install, my dashboard lights and warning bell for headlights being left on haven't worked. I can't find a fuse for them. I also have tried a new head light switch which didn't work either. I checked the bulbs and they seem to be in working order.
All other lights work properly and when connected to my motorhome, the brake lights, tail lights and turn signals work correctly.
