For a hitch for your 1993 Jeep Wrangler I would recommend the etrailer hitch # e98859 as it has great towing capacities and an easy install. With that said Adam there just isn't going to be a way to use a carrier for the motorcycle as your Jeep can't handle that amount of weight. The best solution would be to tow a small trailer with the hitch I mentioned.
If you need trailer wiring too you'd want the Tekonsha part # 118356 which installs easily. view full answer...
