    Lightbulb Help wiring up Car Headunit from Scratch, No ISO

    Hi

    I am looking for some help and was kindly directed to this site as recommended by few members on another forum.

    I have a DVD Headunit that came with my car that is fitted but not wired up as previous owner didnt know how to.

    Problem is headunit does not have any wiring with it.

    I have took a few pictures to show where currently stuck and was wondering if anyone out here able to help match up the 14 pin form the wiring diagram so can start to make an adaptor to fit my car.

    The Headunit has no visual make/model etc. I have made an adaptor between the headunit and my cars audio connections using ATX motherboard power upply adaptor and trimmed it to fit, all necessary olour coded wores as per diagram on headunit are done aswell. Just need to know pin allocation so can wire it all up.

    I did open it up to see if any info was printed on PCB and the following is showing

    The info below is showing on PCB underneath the top 7 pins reading them from left to right

    B+ RL+ FR+ RR+ FL+ ACC ACC

    This might help

    Any form you is very much appreciated.

    Thanks

    Hi

    Am looking at using another headunit in car as amp after fitting my dual screens today purely as this has DVD built in unlike my other.

    Its a chinese OEM unit and does not have the factory harness. It does however have a wiring diagram on the unit and the unit has a 14 pin connection on back but having trouble allocating wiring diagram to the pins.

    I have added some pics of rear of unit and wiring diagram.

    I opened up the headunit to see what was on PCB for better understanding and printed on PCB below both rows of pins are from left to right
    B+ RL+ FR+ RR+ FL+ ACC ACC

    Still not sure on these are the dont really correspond to wiring diagram if I am reading it right.

    Can someone help me out so I can get this wired up, using it as amp between screens and playstation then will replace playstation with android pc once rest of parts arrive.

    Where's that thing from - CHINA? It don't follow any "standard" wiring that i can recognize. I would say buy another one then experiment with that one and if you blow it up - oh well! Not much help but you are going to spend a bunch-a time trying to figure that out instead of enjoying another one that is clearly marked and you can install right away.

    IMO!

    is there a issue with cost of a replacement that you would prefer to try to get this one working over purchasing a new unit? just trying to understand the premise-- personally, i would toss a new generic $30-50 cd deck in the car and call it a day.

    there is also the possibility that the deck is burned up, and they disconnected it to just keep the hole in the dash from making the car look poor-- i'd sure hate to see anyone put a ton of work figuring it all out only to determine the deck is bad...

    LOL - i kept looking at that word and knew what it meant (though misspelled) but then i realized I couldn't think of the spelling myself! Had t look it up!

    Sorry, got too much time on my hands.
