Thanks man!
And not really hey.. I've spoken to someone who has done a fairly similar setup, but he has used less gauges.. Basically he replaced everything that was in the stock cluster.. Without adding any others. But, after speaking to him, I was able to understand the process a lot better. In his opinion I won't be able to get all gauges to fit in the cluster while retaining the warning lights in there original position. Having said that, there's no reason why you can't wire up some LED's to the correct warning outputs on the circuit board and then just locate the LED's else where.. As an example, on the top of the steering column where some people put there turbo timers and such. Still in plain site that way! Personally, I want to move them somewhere a little more out of the way, while still keeping them in my line of site while driving. The original circuit board is used, to keep it all fairly simple. But then, the next biggest issue, which was raised earlier in this thread, is making sure that there will be a speed output reading sent to the power steering ECU and ABS.. Things like that, I haven't had a chance to really look into it as much as I would have liked. (Things came up, meaning I've had to put this project on hold).
When I do get it back up and running, the difference between cars makes is another thing I'll need to take into consideration. It sort of makes it a hard product to 'mass produce' so to speak.. Because of the difference in generations and even the difference in whether on not the car is a JDM Import or an Australian Delivered model. Having said that, definitely isn't something that cannot be learnt and put into practise ;)
But, it's quite a long process and until I get a prototype up and running.. I can't really say anything final haha.
But, I'll definitely keep this thread up to date with what's happening (:
