Hey guys i got an 04 scab that im in the middle of making my own with some bolt on upgrades and such, but im confused with this back up cam that i bought.
The head unit is a chinese double din called 'pumpkin'
Basically an android tablet in the dash, but has all the inputs for gps and back up cam (Rca)

Now after all the wiring i did today for the radio and sub/amp, im stumped on the cam.
I was reading old posts about tapping into a black/pink wire, but there is only two rca cables for the cam, one yellow and one red that has two stripped wires (red and black)

My question is, do i tap into the black/pink reverse lamp with the red end Of the rca cable?

Only reason im asking Is because in the instructions for the head unit, its already set up for a back up cam and has a wire labeled 'back' for the cam.
So im not sure if i should tap into that wire or the black/pink.
Ill attach a photo of the instructions for you guys but id like to get some advice on this.

thanks fellas
