Well, this one is a little delayed, but a while back I started on a project to create a relay box to go in my truck to manage turning on and off things like my amp, cb, power inverter, etc. all from one location without having to reach around all over the cab to manage the various devices.

The control box I have right now only controls three of the relays, and this control box will live in my truck, but the relay box is capable of switching up to seven devices. This way I can use another control box, and quickly grab the relay box from my truck and use it for various other purposes.

I chose to use a standard ethernet cable to handle the connection between the control box and the relay box because of it's convenient management of 8 wire. This allows for one to act as ground and the rest to send a small voltage to each relay. The power is fed in from the control box, that way only one wire needs to run to the relay box for operations.

I ran into this today whilst trying to install my printer on my vista box. I've now got it working, but I'd like you to take notice of a couple things in this screen shot portion.

First, notice at the top it specifically states: Now look for the problem with this page. (HINT: It's at the bottom where it says, "Print this solution"!)
