The next connection is between each air spring and the air line “T” fitting located just ahead of the check valve in Harness #2 near the compressor (Figures 1 & 5). With the air springs Deflated, use a hose cutter, a razor blade, or very sharp knife to cut the air line already installed between the air spring and the inflation valve Install the provided “T” fittings in each air line (Figure 1). Push the air line into each leg of the “T” until you feel a definite “click”. The line should go in 9/16”. Connect a single length of air line to the open leg of each “T”. Cut this piece of air line in half and install another “T” fitting. Connect another length of air line to run from this “T” to the “T” already installed in Harness #2. Avoid heat sources, sharp edges and tight bends (Figure 1).

Now connect the power wire from Harness #1. Route it to the vehicle fuse box. Use a test light to determine which open terminal (accessory, etc.) works only when the key is in the “on” or accessory position (or refer to the owners manual for an available accessory fuse). The terminal should have an amperage rating equal to or higher than the 15-amp in-line fuse. Connection to the fuse terminal will depend on what type of fuse your vehicle uses. If your vehicle uses the barrel type fuse, use adapter #1. If you have the standard spade type fuses, use adapter #2. Many late model vehicles use a smaller spade type fuse, which requires adapter #3 (see Inset A). If adapter #1 or #2 are used, it will be necessary to cut off the 3/16” female connector attached to the power wire and crimp the larger ¼” female connector supplied with this kit. NOTE: Connect adapter to “HOT” side of the fuse (use a test light to determine). With the ignition on, the compressor will turn on and fill the system to 10 p.s.i. before shutting off.

GAUGE LIGHT: Route the white wire for the illuminated gauge to harness #1’s fused wire or to a dash light wire circuit and attach with the quick splice provided. Ground the black wire to an adequate ground. Use the additional wire and connectors supplied if longer leads are needed (Figure 1).
