I'm still not certain what our next step should be. Do we just attach a single wire to a connection inside of the CR-V's wiring socket that will extend the 12v line to the CR-V's positive battery post, or do we also need to connect a wire to the negative lead to extended it to the CR-V's negative battery post or to ground?
If I type fast, I can beat Ron on this one. Use a single wire from the socket to the positive battery post. Ford uses 12 gauge wire for this circuit so you should continue with that gauge. There is a fuse in line in the fuse box under the hood that protects the circuit.
Bob did beat me so I am left to say.....Sounds right by me.
Bob, Just clarifying...."fuse in line in the fuse box" You are referring to protection in the PC.
Bruce, the ground wire should already be in place to support lighting like tail lights and directional signals. I would not worry about the ground wire gauge because the setup most likely considers battery maintenance.
In my 2007 rig, I do wonder if there is an accessory or two (or 3 or 4) installed by PC USA sourced off that ignition-on-12v to tow vehicle. It would explain my situation, and might be the case with you guys too. You just don't know it yet.
