2004 super duty diesel stereo wiring

I have a 04 f350 diesel. Had the 6 disk player in it. Trying to instal after market gps/stereo/dvd player Now the crazy parts..At least in my head..All the wiring diagrams here or anywhere don't explain what the wires are doing.. the main ones I am having issues with are:
solid pink 12v constant
drk GREEN/ purple 12 v constant
BLACK/ red 4 v constant
grey/blue ?v noting on acc or on
BLACK/ green ( i have 2 of these i thought were ground)
black (thought was ground)
the rest i am sure are speaker wires given the same colours appear elsewhere in diagrams

my new deck is wanting :
pink to brake
orange to ill
red to acc
blue to ant (+)
yellow to 12v
black to 12 neg
orange to reverse in
ir brown

If anyone can help me with this I will be forever great full.. now i did have the black red and pink tied together and my truck would try to start right away when turned to accessory. so i discontected that and now truck almost sounds like it is out of time.. so weird Something is really wrong here.. so I disconnected those and all seems to be ok. getting a little gun shy now. thanks again for any input..

should add that there is a total of 15 wires. Thanks again for any directions..

buy the adapter harness for your truck and you dont have to worry about what wire does what.

nice idea but got the unit off ebay (china)..not sure of any adapters..

Did you already hack the plug off?

yes but can always put back on..

pink...accessory, light GREEN/ violet...battery, light blue/red...illumination, black...illumination ground, BLACK/ light green x2...radio ground, RED / black...start signal, grey/black...vehicle speed signal, another light blue/red...steering wheel controls?
ORANGE / light green, light blue/white...LF speaker +,- , WHITE/ light green, dark GREEN/ orange...RF speaker +,- , grey/light blue, tan yellow...LR speaker +,- , ORANGE / red, BROWN / pink...RR speaker +,-.
vehicle may not have steering wheel controls or vehicle speed sense.

thanks ween.. maybe you can help me here with my confusion.. when i test the pink i get 12v continuously.. no acc. also is there a difference in grounds? ie the black on the truck is it a frame ground and the black green ground on the neg terminal? This truck is driving me nuts.. Will try what you have suggested and report back for others to learn..

check power on pink with door open, should follow ignition switch...has retained accessory power from factory. use BLACK/ light green for ground, not thin black.

You bought the truck off ebay from China?

Bottom line: never hack off the OEM wiring harness from any vehicle except in an absolute last-ditch effort to make something work. It only makes your life miserable.

ya thats it.. i bought a super duty dually ford diesel truck off china... came with free shipping to boot...
hey ween you rock... that was totally it.. i was testing pink to power and still had that timer built into it for the power with the doors and radio... total blond moment and thanks again..

I live in an area where product support ie clips, connectors is not great. Rebuilt and rewired a 73 164 volvo with new electronic computer control and well everything and it made this look easy..so just getting a connector for this ford which appears to be a blend in model years where some stuff follows a 2003 and other parts is from 2004..is a waste of time and where is the fun it? Man built it so it should be able to be fixed just needed to figure the logic behind all these wires... thanks again set up is working.
