I had to pull the main tank, so I was cleaning grounds by the battery. I have a red wire connector, 4 hole, by the battery that is not hooked up. It actually has both male and female connectors, but the one side looks closed off. Does anyone know what accessory it may have been for?
Thanks

 

that is definitely the hookup for a trailer. I found mine when i pulled the tank too. It was stuffed away behind the panel where the ECU is located. It was good for a giggle while having to wrestle the tank out

 

I cant imagine someone putting a hitch and towing a trailer with a jag. Maybe for the Harley?? Thanks for the answer. I was hoping it may have something to do with the rear fog lights that I could tap to get the front ones to work
