My thoughts exactly on the MX5 clocks. I like them in the 5, but I think they'd look a bit gash in the roadster, and would be a pain the proverbial to fit!
I was going to use individual after-market gauges and warning lights, and was browsing ebay for some when I saw the mini clocks.
It would have been easier taking that route, but I like a challenge, and it gives me an excuse to design some electrickery
That's right about the Mk2 speed sensor. Although it doesn't appear to go into the ECU on my wiring diagram, maybe they only did that for later models?
Do you mean 'odometer' on the LCD? I'm not sure if you need one or not to be honest

I can't remember seeing anything about it in the IVA manual.
I do want one though, and I'm pretty sure I can get it displayed on the LCD with a bit of work.
