Hi all.
Sorry, I know I'm new here, and I've done a little searching on the forum, but I can't find what I'm looking for.
I've been restoring an 1964 Ford Falcon Ute, learning heaps as I've been doing, and trying to make it as high tech as possible. And my current plan is to have no physical controls, keys, air-con controls, light controls. I want to route it all through an android tablet.
I've figured out how to hook all the speed/fuel gauge/temp gauges into the first of two tablets (a nexus 7). But I was going to get a Nexus 10 and weld in a surround into the middle of the dash. It'll control all the radio/GPS easily enough, but the air-con and other buttons are trickier.
I wanted to get an bluetooth 8 channel relay board, and hook all the physical switches into it,

And cause I can, here's the car I'm talking about:
This is when I first got it (sort of)

Two years worth of work:


And the dash I plan on welding the tablets into:


So does anybody have any tips about getting it working, or reasons it won't? Or if the relay board it the right thing to use?
I'm on a few car forums, but I get very blank looks when I try and talk about this, and I wanted to hear some opinions before I start cutting and welding.
