Sym Projects and gauges question.

[digitalx]

I'm looking to add a bit more realism to my setup, I have received a USB handbrake today so nearing completion.

I have heard that Sym Projects do a Rev Burner, do I need to solder or crimp wires? Or can I use push the wires into the terminals (think theyre called that) and screw it down? I plan to add a speedometer, tacometer and hopefully a fuel gauge.

I did look at getting a cheap car instrument cluster but then saw people having to use Arduino boards, and then I'm lost.

I found a tacometer with red, green and white cables which looks about right. What can I do about a speedometer with these?

I just want the easiest, cheapest solution here.

Thanks.
