83 Level Ride system

I have an 83 Fleetwood and it's level ride light will come on and stay on for sometime then go out, without the pump kicking on at all. I want to tow with this car and need to fix this problem yet have no idea where to start. Would be grateful for any wiring schems or assistance I can get!

Go buy hi-jacker shocks for 60-80$. Then you can fill them up with air to the ride level you want. Also take your dash off and pull that dumb light out. I did and my car seems 100 times better now.

Thanks guy,
Thats what I ended up doing. The level system on the rear was a mess, not worth the cost. The HighJackers at psi and hitch system I now pull with ease 12,000. Lb Wells Fargo Trailer
