You will have to look at your camera and find what supply voltage it requires. I am not sure how many types of oem camera's there are, I just know mine specified 5V 3A
I called the dealer and asked they asked if for an Avalanche/EXT or Escalade/ESV. I said ESV and he read me the specs which was 6V 3amp. So I ordered a converter from 12v dc to 6v dc. I'm adding this to my avic-z130bt which is wired the same way but you put an additional wire from the positive reverse light wire to the violet/white wire of the avic-z130bt to trigger the automatic reverse mode to automactically have your screen display the camera while in reverse. All other connections and wires are still used the same way.
