We don't have instrument wiring for the 04 & later (Vansco equipped) coaches on the Tech Library. Yet. Still hoping AppleJim's plea meets w/success.
Jim- the cluster of three gauges plus the idiot light cluster (dark black oval to right of gauges that light up on initial "Key-On") are by Actia
and come as a set. You probably have one long oval of idiot lights; later models have two shorter ones. You should be able to pull the idiot lights out toward you after removing the screws and read the Actia tag on the assembly. I think you will find the idiot lights are connected to the gauges, maybe by a twisted wire pair. With the part# from the lights, you can contact Actia at the above link and find out what options you have for their equipment.
Removal of the gauges takes more work. Perhaps somebody who has done it can describe an elegant method (aside from hauling out a big sweaty wad of money and paying somebody).
