Seeking wiring diagram for 2009 IC RE300

[ChrisHutchinson]

I've looked through this site with crossed fingers and I haven't yet found the right post or link to a resource with wiring diagrams for my bus.

While free would be amazing, I'm good with a resource to buy one if needed.

Recently I very carefully removed the safety light module and consolidated some of the fan switches since I'll have my interior heat fans connected to my 24v solar system - and despite my care the dash instruments are now unpowered. The wiring in the side panel was a rat's nest with some work done by the previous owner, and it may just be a loose fuse or a connector that came off.

I appreciate anyone who can help me figure this out myself before I go down to my local heavy duty garage who has an hour minimum at $250/hour.

Thanks in advance
