The relays have the same footprint as the Ic's. That is a free on line cad program I used. I just used the existing library and fitted the parts I needed to accommodate my circuitry.

It is gonna work, but the problem remains about the connectors. Shellback was right about the connectors being dedicated. It is hard for me to understand the mentality of this dedicated connector stuff. I guess Chinese labor is cheap. I can work around this, but it want be as purdy. It also makes the install more complicated for the less fortunate.
Gotcha. I dont own a MK TM so I dont have anything to look at, but am intrigued by your efforts. I seen where you stated the Terrova uses serial data for the control, Im assuming you're talking about RS-232 or 485? If the V2 was the same way opposed to cable control, it would be easy to do (footprint wise). But from the reading Im assuming the Terrova lets you use either hence the motivation behind your project.

Nice going. I like figuring out how stuff works and then manipulating like you're doing. Im an electronics tech but sadly it's become easier to just swap out an entire module than troubleshoot the board itself, so I don't get real deep into the circuitry anymore.
