CONTROL PANEL ACCESSORY KIT
INSTALLATION INSTRUCTIONS
Congratulations on your purchase of a new Control
Panel Accessory kit. This kit was designed to provide
inflation control of your air helper springs. This kit will
be an asset to your vehicle, meeting nearly all of your air
supply needs.
Please take a few minutes to read through the
instructions, identify the components, and learn how to
properly install your Control Panel Accessory kit.
NOTE:
The Control Panel Accessory kit can be used with all
air helper spring products. If you are installing an air
suspension system, do not install the air line tubing to the
air springs as stated in the suspension system instruction
manual. If you are adding the Control Panel Accessory
kit to an existing air suspension system, you will need to
deflate the air springs and remove the air line tubing.

NOTE ON CONNECTING THE AIR LINE TUBING:
Cut the air line tubing as squarely as possible. To
connect the air line tubing to the fittings, push the tubing
into the fittings as far as possible. If for any reason the
tubing must be removed, first release the air pressure
from the air helper spring. Push the collar toward the
body of the fitting and the pull out the tubing. To
reassemble, make sure the tubing is cut squarely and push
the tubing back into the fitting.
Install the relay within three feet of the compres-
sor. Nylon ties can be used to secure any excess wire
and the relay neatly into place. Route the white wire
labeled “Switch Panel” to the control panel. Connect
the white wire to one of the white wires on the back of
the switch. The remaining white wire will be grounded
to the vehicle. Next, connect the orange wire labeled
“Comp +” to the red (positive) wire on the compressor. Connect the red, fused wire labeled "Bat +" from
the relay to the battery or another 12V (positive)
source capable of supporting 20 amps. See Figure
"A".
