Sorry, I did it a while ago, seemed simple at the time. It's 9 wires to solder, not too close together, and the parts are cheap. though does take some moderate skill with a soldering iron what you end up with is a direct video feed, pretty much a perfect signal. if you cant do it, you can take the schematic down to a local hobby shop and they might be able to help...or i guess an rf switch would be ok.
