I need wiring schematic for 2008 Express Schoolie?

First time in a Forum. Is this where I ask questions?
I just got a 2008 Express Schoolie that was partially started by prev owner and I want to remove or repurpose switches where the drink holder was.
So, I'm needing a wiring diagram for the short bus.
I'm also going to be adding more wiring for lights and such.
All the plastic panels have been glued and riveted to each other, so it is way too much work to get everything apart.
HELP??? Thanks.

it easiest to go by a chiltons manual for your bus/ chevy express van then you will have all of the wiring diagrams for it minus the bus body wiring.
the book i have for an express covers everything from 1998-2010.
my cup holders or on the doghouse that gets removed to access the engine.

Thank you Jolly Roger.
I am looking for wiring on bus part, i.e. the stop sign, the front bar motor wiring, the flashing lights, etc...
Would that be in there or is it the regular wiring for a standard express van?
Thanks for the help.

For the Chevy portion I’ve used the online GM tech manuals. Supplying the VIN gets very specific info that includes step by step troubleshooting and recall info

This is my bus. 2008 Express. Had ramp for wheelchair, split front entry doos and standard rear emer door. The front gate was removed, the stop sign on the driver's side is gone but the wires still protrude and I understand the flashing red and yellow light up top have to be removed in New Hampshire. These are all switches I want to repurpose. The rest of the wiring has to be modified, like using the dome light switch to come off another battery for lighting, using the stop sign switch to install outside lighting, etc....

My advice to you is to document wiring and abandon it (not remove it). Run new wire for your purposes. Get the Blue Sea Circuit Wizard app to calculate wire sizes. You can probably still use the switches. You just want to know that you aren’t exceeding their rated ampacities (marked on the switch). You could even run heavier loads if you install relays.

the flasher, stop sign school bus stuff was done by your bus body manufacturer.
the chevy manual will not help with that.
in my collins body everything bus related was in a compartment over the windshield.
terminal strips fuses and all wires labeled.

I'll have to take a gander inside of my compartments and hopefully there will be a wiring diagram stuck to an inside wall or door. Thank you.

Those are some great suggestions. I was mostly looking for what fuses each item was using and the color coding of the wires so I could trace it out so I could re-purpose the circuit and switch and maybe even the wires, providing they were of a proper gauge and path. My stuff will be mostly light duty, low amperage stuff.
Thank you.
