Our Liberty has a box near the top of the engine bay that the lighting harness feeds through. It has several fuses and while I was having the air line installed for our MG toad brake, the installer suggested that it might be a tail light converter, though mine did not seem to be functional. Any ideas if this is the case? It has a selector switch on it and the wires in/out of it are clearly for the lighting. I don't have pics right now, but I'll snap one when I get a chance.
thanks,
Devin
