Nope, Sorry! Nothing in a plug in for any Sport, sorry. You will need the converter. The problem is that the truck uses two separate bulbs, one for the turn and one for the stop/marker. On the trailer it's all in one bulb. It's really easy, and I wouldn't worry at all about tapping the truck's wiring. Make your connections with Scotch-lock connectors inside the taillight cavity. That way, you'll have plenty of room, and the connections will be out of the weather. On some vehicles, we need to upgrade the flasher to a heavy duty one to keep it from blinking too fast, and there is a note in the instructions-
Do not exceed 2.1 amps per stop/turn output (equivalent of one trailer stop/turn bulb). Applications of more than 2.1 amps require a power converter.
In other words, if you have a pretty normal trailer, you'll be fine. If it has electric brakes or multiple lights tapped off of the main light circuits, you need more.
The basic converters usually run around $16, and will get you a "4 flat" plug. If that's all you need, you're done, if you need a 7 way, or 6 way, you can add one that will plug into that 4 flat. The outlet will then just bolt up under the bumper wherever you can get it. Those run about $25.
FWIW- Your '93 would be the same way if it didn't have the factory tow package. Hoppy shows a "coming in spring '08" plug-in for that one.
