Air Suspension Wiring Help Needed

[nitrus rush]

I was just wondering if someone could post a wiring diagram for the auto leveling suspension system on a 1999 GMC Envoy. If someone did I would really appreciate it. Thanks.

What is it doing or not doing?
If it has a problem there should be codes set.
Check for code and post back code no.

I'm just trying to retrofit a different Delco compressor with a different plug and I need the wiring diagram for my Envoy. Thanks.

You did not say what yours is doing or not doing.
Every time I try to retofit something it does not work out good.

Wiring diagrams can be found in a factory repair manual or a all data online sub.

pump motor pin out on yours is
A - pink is fused ign 1
B -white is exhaust solenoid output
C orang is fused
D yellow is relay output coil
E orange is fused battery
F not used
G black ground

Unfortunately I don't have an Alldata account. Is there anyway someone could attach the diagram for me? Where did you get that pinout information from if you don't mind me asking?

[MT-2500]

The pin out info I posted comes from Mitcheel on Demand.
It is usually a copy from the factory manual.

Your public libary may have some good car repair info .


Hit the link below and for about 25 dollars USA plastic and 10 minutes you can have a All data Online sub.
http://www.alldata.com/products/diy/index.html
With all of the wiring diagrams and repair info on it.
But the All data onlne sub's are a one car deal.
If you are trying to fit another car pump on it you may need the wiring for it to.
The second All data sub's ore 1/2 price or less right now.

Sorry about it but.
Most of the wiring diagrams are copy right stuff so we can not pot them in open forums because of copy right laws.

If you would tell us more info.
What is you old pump doing or not doing we may be able to help more.
