Wiring diagram

Hi All, I'm trying to source a wiring diagram for my 2008 R400 specifically the gauges but any and all input is welcome. I'm building a complete new harness.

I don't have a diagram but...Can you use painless wiring like this one?

Thanks, I'm already using a custom bespoke harness for my AEM ECU I just need a wiring diagram to make the new dash harness. There are some issues with the reference values that the Caterham gauges use (5v not 12v), I don't really want to change the gauges I like the look I have now and don't want to have to buy a new carbon dash.
