Auto to Manual Swap Wiring Help

[Jeff240sx]

Hey guys.
I'm trying to get my car running, and I need some specific wiring help.
I'm mainly stuck on the "Connect the auto thinggy behind the fuse box together," and the backup lights. I've gotten everything else done.. but my car won't start now. Someone please help! Pics would be awesome if possible, or just really good descriptions would help a bunch.
Thanks!

there are two thick wires one black and one white they are in a plug below the pass side relay box these wires need to be jumpered together
the plug has only these two wires in it so it should be rather easy to ID

Yea. I got that shift thinggy (2 wire plug) a couple days ago.
Now I'm stuck on the backup lights and speed sensor. Need help!

I used a manual lower harness (SR swap car) on mine to make sure every thing plugged in

IIRC speed sensor plugs line up or at least have the same plug on them i am unsure on the backup lights though
