Oh man i've been doing some reading to figure this out.

If someone can help answer a few Q's please.
I have everything connected to the tv tuner and have a white wire coming out saying 'camera +12v'.
I have splice yellow/white and brown in the trunk hatch.

So i have a yellow/white and a brown from the car
I have a white from the tuner wiring

I have a red and a black coming out from the back of the camera - i dont know where these go.

Is purple pink the wire for the reverse lights or is it the yellow white?
I think I need a relay - what does it do?

This is where I am stuck, I dont know what to attach to what to make it all work.
I read THIS POST and I think I am pretty close to finishing the whole job with a little help from you guys.
Please help
