Short answer - no, they don't Longer answer - Honda's advertising is misleading in this area. The RL wiring harness includes wires from near the brake pedal back to the rear for electric brakes, and another from near a fuse panel back to the rear for charging a trailer-mounted battery, etc. But the wires all "dead end" in proprietary connectors.. Commando Car Alarms offers free wiring diagrams for your 2006-2011 Honda Ridgeline. Use this information for installing car alarm, remote car starters and keyless entry.
A single diagram? So many circuits in modern vehicles, I've not seen a "full" wiring diagram for a vehicle in many years. IMO your best bet is $10 spent for Honda Service Express and do a lot of file saving in 24hrs (or $50 for a month and relax)..
