What I've got: the wires going from the Transmission / Transfer Case to the molex connector / harness connector thingy:

Wires going from the reverse lights to an area by the parking brake:

The two light green wires by the parking brake are labeled "to brake lights" and to "brake lights power +B" or something like that. When the "to brake lights" gets 12v the brake lights come on.
My questions:
I'm assuming I need to get the two green wires through the firewall. How do I do that? Shouldn't they be connected to the back of the fuse box (or that relay?), with a harness coming out the other side to connect to the Transmission side? I can't see anywhere on my engine side of the firewall that has any wires labeled for the backup / 4WD lights or any connectors that look anything like the plug coming off the tranny/xfer case.
edit: Please fix the email notifications for replies! I don't want to have to check this thing every few hours or forget about it being here.
