I picked up the Escape Wiring Kit to hook my Yeti PRO 4000 into my van build and it covers basically every connection I needed. You get the HPP+ 12V flying leads, the HPP+ solar input cable, the TT-30P AC output for an RV, and the 8mm DC input for charging off the vehicle. All four runs are 8 ft, which was enough in my setup, and the 10 AWG wiring feels solid. Labelling the cables would help. Good kit if you're integrating a Yeti PRO 4000.
