Thanks for the tips guys, but no joy- unfortunately. I went out to the shop this morning before work, and looked at the main wiring harness. It's not pre-soldered onto mine. I even checked harness #2 (the 'options' harness) and it's not on that one either.
I am very meticulous in pre-inventory and in parts storage. Darn thing just isn't here, and since it wasn't on the printed inventory list from Van's, I never knew it was non-existing. Since it wasn't on the list, I think I'll just call Van's and get them to send me the right one.
Thanks for the replies.
