This install is much more of a pain in the @$$ than I expected. There is little to no room under that steering wheel to work with. The plug, like rufftsuff said, is almost on the firewall, centered up with the steering wheel. It's the only plug in that area. Just know that it has a cap on there which looks like part of the plug, you have to remove that first. The other end plugs into the upfitter switches. It's much easier to run the wires if you pull out the trailer brake controller (if you have one), the lighter plug fixture, the bottom panel of the dash, and the side panels by the drivers door. I still had a hard time getting my hands up under there and running the wires. Didn't make it much easier that I have a Viper alarm and all the brains/wires/relays were right in the way. I didn't use the metal bracket that came with the relay box, I removed it and used a zip tie since I had limited space.
Once I zip tied the relay box I ran the harness wire behind the steering mechanism and plugged it in. Then I ran the end connector up over to the upfitter switches and plugged it into the back and placed the switch panel in it's place. Then I put the trailer brake controller back in, the lighter socket fixture, and the side panels. I couldn't find most of the crap listed in that set of directions so I found and open hole on the metal frame piece under there and used a stainless steel bolt and nylon locknut. It took alot of small turns with a driver and I had a small pair of vise grips locked on the locknut, but once all was said and done I tested it and it works fine. Last thing was to replace the bottom panel underneath the steering wheel. About an hour of time. Hope that helps.[IMG]
