Well I want to install a backup camera to my hyundai elantra 2008 gls, but I have no idea where to begin to look for it. Also, I never hooked up the pink wire and since I was going to try and install the camera I figure I could finally install it, but I have no clue where to look for that either. Any help would be greatly appreciated. My headunit is the x930bt

this is not a pioneer-specific question, but a hyundai specific question. You want to find out where the "reverse wire" is. You will probably have better luck on a hyundai/elantra specific forum, or by looking in service manual wiring diagrams for your car.
