1996 Oldsmobile Auto Leveling probs

Hello im wondering if anyone could tell me the location of the relay that controls the air compressor motor for a 96 regency elite, that has the air compressor under the chassis behind the rear passengerside tire.

We currently cant get the computer module to engage the air compressor, but we can hotwire the air compressor so we know it works.
Fuses have been checked as well. Im trying to find the relay that controls the air compressor and would like to know where the wiring from the leveling sensor goes to in order to check that wiring.

Any help is appreciated, ty.

Aaron.
