For those that are curious. This is a diagram of the warning indicator lights on my 1986 GMC school bus. Mine is a little different than what’s in the service manual, but closely matches the top version. Mine reads: Left Turn : OVER SPEED : BRAKE : Right Turn OIL PRESSURE : WATER TEMP : LOW AIR : CHECK ENGINE
You can see the lower version has options for hydraulic brakes and the associated brake booster.
To whomever is curious, this is the vacuum diagram for a 1986 GMC/Chevy school bus with a big block 366/427 V8 gas engine. Sorry this the best picture I could get. The dark spots are inside the sticker and won’t clean off. Hope this helps anyone that needs it.
