Hello, I just removed the oem trailer hitch from my 98 sport because it was rusting from the inside. The hitch I replaced it with is a Curt for cherokees. Now I have the big round 7 pin connector hanging there and no place to mount it. There is a connector that can seperate the 7 pin to remove it. Does anyone know if there is a adaptor that would plug into that connector to make it a 4 pin. I do not need the 7 pin and would like just to have a 4 pin being it is much smaller. Thanks for any advice.
