It's pretty straight forward. You should have a pigtail that came with your truck's tow package and a pigtail with the prodigy. Solder these together so you have a plug to plug pigtail. Now, stand on your head in the driver's side floor (not kidding) and look for a harness that is blue taped near the steering column, way underneath the dash. Pull down the plug to release it from the tape. Plug your newly soldered pigtail into that plug. Now decide where you are going to mount the controller. I used the provided click-in bracket, but some people just use Velcro. I have mine to the right of the steering wheel and just left of the center console. You should experiment with this placement first. Some people complain of bumping it with their knee. This location works fine for me and I am 6' tall. I unplug my controller when not in use and store it in a padded pouch in the center console. This further lessens the chance of bumping it. If you have any other questions, just let me know. Have fun.
