Much appreciated.

Left one looks like PTO. The right one I don't know. Amber Lamps?

The one on the left looks like it centrally locks the differential.  The one on the right....clutch start cancel switch maybe?

Those are the idiot eject buttons.  They wanted to make sure with you, so they put two in.

pto? diff lock? Never seen those before.

Owner's manual.  It's that "book" in the glove compartment.  Yes, I know, it has pages and printing and is not a computer screen, but that's how they did things back in the day.

First one is "FO Time", the second one is "I'm Foing".

Use with care, and blade to 45.

left is a central diff lock/tcase lock, the one of the right I would guess to be a back up sensor on/off ?

I'm going to go with left is PTO control and right is air suspension control. They look like rocker switches.

If it had an owners manual I wouldn't be asking.

Although, if I didn't get smart ass responses, it wouldn't be ARFCOM.

I've confirmed the left is a diff. lock. I'm hoping that the right one is a descent control.

Thanks for the help fellas.

I think PTO was removed from the Allison in 2005 or so ( to save a few bucks, wtf?) but it was available on chassis cab trucks and if that right toggle is a back up warning light he may have a chassis cab.

The one on the left is to disable NASCAR mode––it enables the vehicle to turn right.  The one on the right activates the GPS restaurant locator, as indicated by an ear of corn on a plate.

GM did away with rocket pods as a concession in the last round of union talks, and switched from oil slicks to roofing nails after intensive market analysis back in ought-two.

Sheesh.

Anytime you see what looks like parentheses around a circle it is a brake system icon.

The puff of smoke in the middle indicates exhaust system.
Your truck has an exhaust brake installed (Jake Brake) it looks like.  Is that what you guys are calling "Descent Control"?

I'm almost positive every GM vehicle comes with oil slick, or antifreeze slick, standard.  Most are automated however.

left is problably a transfer case lock/unlock.
DO NOT UNLOCK your transfer case unless you're familiar with the effects of it.
I won't say another thing, except READ THE MANUAL

I would agree with the people who actually helped lol. Left seems to be the transfer case lock which would probably put you in the super low 4 wheel drive. Just a guess but would probably make front and back wheels turn at same speed and very hard to turn and stuff.  Had a friend who had a H2 and with the super low 4 it could pull anything lol. I watched him pull a work van out of a snowy ditch that my buddy couldn't get out with his super duty with lots of stuff done to it lol.

The other still confuses me seems to be a pto does the truck have a dump bed?

transfer case lock and exhaust brake would be my best guess as well.



I think those had options of PTO's as well, but the icon for those looks very similar to our beloved arfcom boltface logo.
