I have been trying for sometime to figure out what to do with my original
air system on my 1978 Royale that the PO had modified trying to upgrade it
from and EL-1 to an EL-II system. When I got the coach all the wires going
to the compressor and wires from the height control valve had been cut off
by the compressor. Since I am an electrically challenged one I new I had a
real mess on my hands. But, thanks to those of you who responded to my air
system questions a couple of months ago I found a solution that works for
me. Particularly, big thanks to Bob Burkitt and John Shotwell for their
input.

What I ended up doing is installing a wireless air system. All I needed to
do was figure out which wire was the hot wire from the battery, ground wire
and ignition wire in the mess of over a dozen cut off wires that were laying
by my old compressor. Even the electrically challenged one was able to
figure it.

So now I have an air system that I can control my Quadra Bag System with a
remote control that is about the size of a pack of cigarettes. It has two
programs that I can set whether I am running heavily loaded or a light load.
I can raise or lower each side's air bags independently of the other or both
at the same time. When I am finished dry camping and have previously raised
or lower one side or the other I can press program I or II whatever I need
and the coach rear ride height readjusts to height I have set for travel. I
can even stand outside of the coach and raise or lower the rear of the coach
with the remote.

It is nice to finally have the air system working so that I don't have to
use my plug-in compressor to manually air up the bags. I can now travel
with the air bag valves open. If I were to loose any air the system
automatically comes on and readjusts to the programed air pressure setting I
have it set to. If the air system compressor were to fail I have it set-up
so that I can still manually fill the bags with my old plug-in compressor.
