What doesn't match on the trailer wiring? Basic trailer wiring. http://tse1.mm.bing.net/th?&id=OIP.M...amp;p=0&r=0
If it's a difference in connectors any parts store will have adapters. I also would suggest just setting the engine on the floor of the trailer with the pan sticking through the center of an old tire and tying it down. Transporting it on an engine stand is a bit iffy.
