You should have a 4 wire flat connecter,that will connect under the bumper. I had a 98 Ranger that had that style connector, factory from Ford. The only issue you may have is that the bumper on the Explorer may be to high. I towed my boat off the Ranger's bumper once and the boat trailer was all over the road,the tounge of the trailer was too high. After I put a receiver hitch on my truck it towed like a champ.
