[quote=sahib]If you're lucky and your van came with a factory wired trailer light harness like my '99 did, it should be capped off under the van about two feet from the rear bumper toward the passenger side. You'll need to find a plug to fit the one underneath and make up an interface cord for the trailer plug. I got mine at OK Auto and it worked just fine. If you're not so lucky, you'll need to purchase a wiring harness and tap into existing tail-brake-turn siganl wiring on the van. I have one of these and I'd be glad to sell it to you if you need it. I bought it before I found out I had the wiring in place. Let me know, I'm willing to negotiate if you need it. It's by Hoppy. If you need that plug I can look it up and give you the number I think. Ford does have one made up but you may not like the price.

is the after market plug and harness the same as the factory one?
