Left side of the engine bay, under the PS reservoir, under a plastic cover. Pops up with a tab.

That's the best I can do without going outside and snapping a pic!

Pull off the cover, it's the smaller of the two, should be on the right side (your left if you're facing the truck) Before you pull the lever on the connector, spray some type of cleaner to clean the debris, then some lubricant (WD40, penetrating oil - just a little) to get it ready to come off. Mine were covered in dirt and didn't want to come off easy. Cleaned with some penetrating oil they came off easy.

It is in the engine bay on the driver front side of the motor. Look at the battery and just below it is the ECM/TCM on a bracket right beside the motor.
