I installed a NCCO charge plug in my 2015 P2, I asked BASS Cat to install one, they do not offer it. I had one for 25 years in my Gamblers. Buy the NCCO, it has a pig tail, got it from West Marine on line,about $ 15, drill a 2 inch hole with a new hole saw ( sharp), be sure you use tape over the area to stop chipping. and be sure that there is clearence in the comparment area to run the pig tail, 3 small screw holes to drill assemble, and plug in your charger. Took me a half hour. I dont understand why BCB doesnt have them atandard, Nitro and others do. Hope this helps
