88 A2C all the way home.

The loose 85 should go to the Low Air warning light on the gauge board. Older A2 duces did not have it it was a add on and I think standard on the A2C.

I have the original gauge cluster less the gauges; it doesn't have any extra lights on it.

I just had to re-wire a truck that came from GL, as all the gauges had been ripped out. I could have sworn the 27 circuit was the 24V power for all the gauges (marked "IGN" on the back of the gauges) and that 27 was all that went to the voltmeter.

Let me check, brb.

EDIT: Yes, 27 is the voltage that powers the gauges.

Thats right- My 5 ton is wired that way also

Try this site for wire numbers. AMG(Brandon ) keyed me on this one.

Update.
I started to single out my rears yesterday... after looking on here and other sites for geared lug wrenches I decided to try taking them off with a good old fashion breaker bar.
It was so easy a caveman could do it. Glad I saved myself 160.00.

For now I am leaving the hubs un-flipped as I am still undecided what tire combo I will be going with.
