stereo reverse wire

stereo reverse wire
I've got a 2004 Lariat with factory sub. I got a new sony deck and a backup camera, so my question is: Is there a wiring in the factory stereo harness for reverse? Or do I have to tap into the reverse lights wire?
Also if anyone knows of a wire diagram for the stereo harness, I searched and found too many different ones that I didn't which one to take! I am just confused in hooking up the factory sub, and steering wheel controller can bus thing. Any help is much appreciated, thanks

I tapped into the reverse lights for the trigger, for the camera power, I ran a extra 12v from the red radio harness to the camera so I could watch it all the time while towing instead of just while reversing.
Here is the correct harness for the audiophile radio with factory sub.

Thanks guys!
Actually I have the harness that works with the factory sub and has the steering wheel can bus controller built in. The problem is that it came from a different stereo manufacturer.
So all I need to know is which colour/position of wire is which for all three of the factory stereo harness plugs. Once again any help is appreciated!

As stated above, search for my posts on the subject, the color of the three wires is in one of my posts. Im pretty sure its the Red, Black and the Blue wires off the wire harness but look at my posts, or use a multimeter and find a ground, a switched power source and a remote power for the amp. This is off the top of my head if you don't find my posts. Then you would also have to splice the signal cables from you factory amp into a RCA jack, very thin wires, one to the center wire of the RCA, one to the outer shielding of the RCA cable. If you get a pop sound when you turn the radio on, you need to add a resistor to the Blue remote amp wire.

I finally got all the wires figured out. Now I need to know what the resistance has to be to bring down the sub enable wire from 12v to 5v (to avoid the loud pop). I dont know how much current is flowing through this wire so I can't really use ohm's law. Does anyone know what resistor to use?
If I did assume 12v and 0.1 A then that would mean a 120 ohm resistor??

I've looked into this further and found that using two 1K ohm resistors works. I also bought a 7805 voltage regulator for about $3 so I think I'll use that instead. I also got a 100 pack of 1.0K ohm resistors for $3.50! So that issue is solved
One question remains for me: I looked at a wiring diagram for a 2005 model (mines an '04) and I found that the backup lamp wire is DK GRN/YEL. I opened up the center consol and found some wires just not that green/yellow one. Is the backup lamp wire located somewhere else? Or is it a different colour for 2004?
*I'll also be tapping into a hot wire with a switch to manually switch the camera on
