backup camera mod?

Please help.....

after using the vr3 backup camera on my dad's Tundra for 2 yrs, the little monitor finally gave up. I am trying to use the existing wiring harness so that I can stlll use the camera and dont have to rerun any new wires for the new monitor.

I have an extra 5.6" monitor and was wondering if i could tap over the wires from the small monitor(vr3 monitor) into the 5.6" one. I have np working on a new deck.. but this video stuff just beats me right up.

any help would be greatly appreciated.

Thanks,
Sanson
