I've had my Jeep 3 years and the PO had a mess with the wiring under the dash. I haven't helped any as I've tapped into some random hot wire to power the switch for my on board air, as well another circuit for sound bar, CB, and winch switch.
I want to clean this all up but don't know where to start. What's the correct way to get a 12 volt feed that is switched on with the ignition? and how many accessories should i be running off of such a feed?
THere is a 5 prong connector under dash that wasn't hooked to anything. Two of those prongs have power with ignition so I have one powering the soundbar and one powering the winch switch. My CB is left powerless until I get this figured out.
Also, typical toggle switches you buy have 3 prongs. Is the purpose of the 3rd prong to serve as a jumper to another accessory switch?
I'd really like to put in a CJ dash at some point, but that's probably a ways down the road.
The previous owner has all kinds of crap tapped in to various wires which I don't know what they'd be for because there are no accessories at this point in time except what I've mentioned.
The previous owner did have an after market stereo which wasn't wired in at all and there was also an after market cruise control that I took out.
I don't have a stereo head unit, just the soundbar which has a microjack input that I plug into my iphone for tunes.
With the way the wiring looks, I'm amazed that everything works.
