Does anybody have a diagram of the air suspension system of a 99 expedition 4x4 with 4-corner lls?

Where can I find one?

I'd like to know where all the air lines, solenoids, etc. are located so I could attempt a leak test. My chk susp lights up after about an hour of use normal driving and a few minutes of rough roads. Maybe a leak somewhere causes the compressor to work overtime.

Thanks.

 

looking for the same thing, did you ever find a diagram?
