Their website has conflicting/insufficient information in the support pages.
It list 2 sets of wiring info :

single connector style : details only one illumination connections and makes no mention of colour
4 plug connector style : details a choice of 2 connections for white or amber illumination choices

I want an amber smoked gauge to match my 2007 STI swoosh/defi style dash.

I have contacted Graham Goode but had no response.

I have contacted innovate and got a response that the latest gauge is single connection BUT further investigation shows that the new gauges in the same style that support boost/oil etc.... have a white/amber choice, so this doesn't satck up.

I don't want to spend £80 on a gauge to find it illuminates white only, as I have that already with the G3 gauge I carried over from the previous car.

cheers
