Speed sense will be behind the radio, grey/black, and the reverse is black/pink in the driver's side frame harness, so roll your butt under the truck and grab it at the "T" for the transmission control harness. The harness runs along the crossmember under the driver's seat. Same color, black/pink. You can also run to the taillight harness. Wear safety goggles, since Murphy's Law states that all the crap under your truck will go directly in your left eye.
