    ok, it looks like you have a A/V monitor with 2 RCA...err... coaxial inputs.

    how about for the monitor itself:
    RED-12V
    BLACK-GND
    RED-inside RCA AV1(2?) Plug inner
    RED-outside RCA AV2(1?) Plug outer
    Brown-ACC?

    and that other thing... I'm guessing but:

    Red-12V- goes to red
    silver-gnd- goes to black
    Red with pink goes to one of the 2 A/V inputs outside to outside, inside to inside.
    orange??? ACC? -goes to brown?


    Something like that? I don't know for sure, I've never dealt with that brand.

    Your AM-056PN wiring?...

    Cheers!

    Did you ever get the AM-056PN wiring identified? I have a couple of these monitors as well and I took one apart to see if I could figure out the connections, no dice I hope to use the remaining monitor w/ a color underwater camera as a fun project - trying to connect 12VDC and and RCA video signal connector - had no luck at all - perhaps you have?...

    Have a great day!

    am-056PN/PP-C wiring solution

    Hi-
    I have one of these that I just got working. First of all, the wiring colors do not map to what you would think:

    Power:
    Black: +12v
    Bare wire in outer casing: Ground

    Signal lines:
    Red: Video signal (outer wire is video signal ground)
    Blue: Audio signal (outer wire is audio signal ground)

    Unknown:
    Brown wire (just leave unconnected.)

    To figure this out, I used a variable voltage power supply and connected it to what I thought may be the correct leads and then slowly turned up the voltage while watching the current. When the current starts to increase quickly without the voltage increase then you know that this is a short and you back off before doing damage.

    The red and blue wires are coaxial and so you should never apply power to these. You may have damaged your unit but then, maybe it was protected and you are ok. You'll just have to try!



    Have a nice day!

    Definitely not intuitive... I'll give it a try; I hope I didn't fry it when I was trying random connections in frustration (I had given up on it by that time)

    Thanks!
