There latest speedo and rev counters come with built in warning lights (sadly not shown on their website). Not having the extra LEDs makes the dash a lot more tidy. The speedo has handbrake, charge and oil pressure warning lights and the rev counter has the other 3 (left/right indicator and hi-beam)
I've made a temporary dash to help sort the wiring out before I fit the full dash - much easier to take in and out.
Starting to draw up a wiring diagram for it and buy some multi-connector plugs to make it easy to disconnect all the dials - it'll also help with keeping the wiring neat and tidy for Mr. IVA man, as under-dash wiring can get into a real mess :-)
