Really though I'm not sure what "plug ins" you are talking about. My SLT has two power outlets one is always on one is on with ignition on. I think the only other "plug ins" on my truck are the OBDII connector and the radio's AUX input...
I know what you mean by not reading the Owners Manual
Your eyes glaze over after about 10 pages & your brain doesn't register 1/2 of what you read, mostly because of the Terminology they use.
Sooner or later you are going to have to read at least parts of the manual
I waited until i had my Ram almost a year, before i opened the manual to find out why certain lights would come on now & then.
The radio section interested me most, so i had to wait for a semi truck one day & i started playing with the radio & opened the book, that is when i found out that i could give my radio verbal commands & that changed my whole experience with my radio & the Navigation. I don't have a Smart phone, although it is smarter than me, so i have not read up on Smart phones & the plug ins for them
Take some time & read your manual little by little & just read the sections that you are interested in First
Well we can all guess that the OP question must have something to do with the 12V plugs, both continuous powered and ignition powered because I have one of each. Or perhaps the 110v inverter plug on the dash. Hopefully we have not scared him away, cause if he would clarify his question I would be more than happy to provide an answer and save him having to look it up in the manual.
