The GOODbox
No I would need to measure the voltage on your car while it is running. If you think you can't figure it out, your best bet is to ask someone you know who is more familiar with this kind of stuff
since the display reads on startup im fairly certain it will work

Hello,
You mentioned that these weren't compatible for the mazda3's - does this include the speed3's too?
Is it because you dont have the instructions for the MS3's or was there an actual wiring problem??
I really want to jump on this and pick one up if it will work.
Thanks!

i kid, i kid.
not cool... 
Thanks for the PM pieter3d, will have funds soon! Great product as I said before!
In the meantime, I know he has very detailed install instructions, but if anyone can find any tricks or anything while installing, definitely post up!

Do "modern" cheap gauges work differently? IE, by internally incorporating a constant-current power supply to produce a voltage that varies with the changing resistance of the sensor? If that's the case, then tapping the voltage line of the gauge will work if the signal range falls in the 0-5V range. But then, having the gauge installed is required to get the Goodbox signal, which kinds defeats the purpose of having a Goodbox in the first place.
It seems to me then to get an oil pressure or temp signal without having a gauge installed either requires a little independant constant-current power supply to run the sensor circuit, or using battery voltage together with a little ammeter with an appropriate voltage output.
Am I thinking right or am I stuck in the Edison-era?
(Payment sent by the way!)

HiFlight, all you gotta do is look
this is just a random pressure sensor i looked up

if you know what you are looking for, you can put damn near any "gauge" you want on this thing... 0-5V output is so damn common

Good find. What I was trying to point out is there's a bit of a disconnect in the discussion. Page 8 and on in the instruction manual tells what to do with a 0-5V signal, not how to get that signal. What you can't do is wire the goodbox to a standard sensor, at least the 3 different versions I've gotten from summit, glowshift and ebay; they all vary resistance. To make that kind of sensor work, you have to add some electronic stuff. Or, a much better suggestion, use a sensor with a native 0-5v output for the Goodbox as you showed, but then a standard gauge won't work with that. Getting both to work, like 9krpm was talking about, would require some cleverness.
yeah that will take some doing. it wouldnt be hard from an electrical engineer point of view, but prolly more than most people would want to DIY
Well done and congrats Dondo, first installed! Also good work on quick shipping from Pieter. He's been great organising and shipping to Australia and I can't wait for it to arrive.
I'm interested in this too. I'm planning on hooking up oil temp, but not sure exactly what will work with it, given that I don't already have a gauge.
I still have a couple of weeks, while my unit flies over the ocean, to find a temp sender and sort out potential electrical issues as above.
