WARNING!!! WARNING!!! WARNING!!! WARN-
ING!!!
If you plan on wiring the AVSREC4 to control an adjustable air suspension system, you MUST install a relay
to inhibit control of the suspension while the vehicle is running. You will only be able to control the air
suspension from the AVSREC4 while the vehicles ignition is turned off. In the unlikely case that someone
has the same transmitting code as you or the AVSREC4 simply malfunctions, this safety relay will discon-
nect power from the other relays while the key is turned on. If you do not install the safety relay or if it is
not installed properly, serious injury, property damage and/or death may occur! DON’T BE STUPID! IN-
STALL THE SAFETY RELAY!!!
PLEASE READ!!!

If you would like to have up/down control over the rear air suspension then copy the diagram below by adding an an addi-

Wiring The Receiver To Any AVS ARC-9 Air Ride Controllers

Connecting the AVSREC4 receiver to any of our AVS ARC-9 switch boxes is as simple as plugging in 2 wires and adding a
relay for safety. If for some reason the receiver was to malfunction while the vehicle is in motion, an accident could result
from it and cause property damage, personal injury or even death! INSTALL THE RELAY!!! Adding the safety relay will
disconnect power to the switch box while the ignition key is on. In most states it is illegal to adjust a hydraulic or air suspen-
sion system while the vehicle is in motion anyways.
WARNING!!! DURATION OF OUTPUTS: when you activate any of the 4 outputs on your AVSREC4 they will
be on for approximately .8 seconds or 8 milliseconds. While that does not sound like a very long amount
of time, it can be to
