Pinnacle - Connect Tow Battery to RV Battery

I want to install a 4 AWG battery connection between my Pinnacle and my F350. It will be a second, 2 pin umbilical between the two. A quick connect jumper cable if you will.

My question to the forum is how do I pull that wire from the RV hitch area where the existing tow vehicle plug-in cable back to the battery compartment. I have not started pulling things apart yet, and thought it wold be a good idea to ask here first!

Many Thanks!

I pulled a wire for backup lights on our Eagle. What I did was disconnect one of the wires off the embilical connection at the king pin and found where the wires came in to the front compartment. Wiggled it back and forth to make sure it wasn't tied down in the overhang. Taped a cord to it at king pin end and pulled it into front compartment slowly. Then tied and taped my backup light wire to it and used the cord to pull the original and my backup light wire back out to the king pin.
Worked for me on our trailer. Reconnected to embilical and hooked up the backup light wire to the center conductor in the 7pin connector which was a yellow wire that was in the embilical.

Livin the dream... Retired!
