I've got a koolertron camera too, hooking up to a new jvc kwavx-748. The head unit has a wire that says reverse signal lead, something like that, and it has a yellow camera wire as well. I hooked up the camera, which has a yellow video cable,and a power cable, which has a red wire and a black wire inside. I ran the yellow cable to the yellow camera in on the deck, and connected the red wire to the light green wire running to right reverse light, and connected the black wire to a ground on the chassis inside the rear compartment. I also ran my own wire from the green reverse wire in my taillight assembly to the deck, and connected it to the reverse signal lead. I get the camera to work when i shift into reverse, and it automatically interrupts whatever I was doing to show me the camera, great right, but i cant get a picture when I click on camera when im parked, or driving, etc. I know that you are supposed to see camera whenever you want to if hooked up correctly, no support or directions from company, go figure, so I disconnected my own wire I ran from reverse wire to the reverse signal lead, and figured it needed remote power instead, whenever deck on, cam on right, so I connected it to the remote wire I have powering the deck, and viola, I get picture whenever I hit camera. The problem now is, reverse lights stay on when deck is on, so I cut my wire in half, reverse lights went off like they should have, but I can only see camera when I click on Camera and then put it in reverse, it doesnt interrupt like it did before, it will continue playing dvd while in reverse unless I hit camera to switch modes, please someone help. Im lost.:hopeless
