I'm a bit scrappy at soldering, though I don't mind giving it a try - I'm okay at it, just not ultra tidy! Would it be easy enough to do? I'm guessing that it would be a case of opening up the KVM box, locating where the 2 button pads are... then, I guess there would be a ground and 5v solder point for each and you just wire a button to each? Though, that wouldn't be ideal. Or perhaps I just mount the original 2 switch/button from the KVM on the outside of the cab or perhaps just buy a switch... I don't know, I guess I will just have to analyse what can be done and conclude which path to take! I just don't want to many switches/buttons on the outside of the cab - it will start to get too busy and complicated.
Thanks for your help.
