b.  In some cases, a hole may have to be drilled to allow access for the harness. Drill 

a 1” diameter hole and install the provided grommet (fig. 8). It will be necessary to 

seal any grommets or holes that have been cut, drilled or removed so as not to allow 

elements to enter the cab area of the vehicle. 

c.  When routing wiring harness #2 from the compressor, it should not be routed so as 

to lay on, or near, the exhaust pipe/muffler/catalytic convertor of the vehicle. Routing 

along the top of a crossmember or over a heat shield is recommended.

7.  Connect wiring harness #2 to wiring harness #1 inside the vehicle by connecting the red 

wire from harness #2 and the banded and no tape air lines to the low pressure sensors. 

See fig. 5 for air line and electrical connection.

8.  The next connection is between each air spring and the air line “T” fitting located just 

ahead of the check valves in harness #2 (fig. 1 and 7). 

a.  With the air springs deflated, use a hose cutter or razor blade to cut the air line 

already installed between the air springs and the inflation valves. 

b.  Install the provided “T” fittings (fig. 1) by pushing the air line into each leg of the “T” 

until you feel a definite “click”. Each line should go in 9/16”. 

c.  Connect a single length of air line to the open leg of each “T”. Bring each of the lines 

to the “T” fittings in harness #2 just in front of the check valves and connect as shown 

in fig. 7. 

d.  Route the air line across the chassis from the far side over the exhaust system heat 

shields and along the frame up to the compressor. Avoid heat sources, sharp edges, 

and tight bends. 

9.  Connect the power wire from harness #1. 

a.  Route it to the vehicle fuse box. 
b.  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. 

c.  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 with fig. 1). If adapter #1 or #2 are 

used, it will be necessary to cut off the ¼” female connector attached to the power 

wire and crimp the smaller 3/16” female connector supplied with this kit. 

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.

10. Connect the gauge light.

a.  Attach a ¼” female connector to both the red and black wires. 

NOTE

fig. 8

After the hole is drilled and before 

you route the harness to through the 

firewall, insert the grommet and “walk” 

the material around the inside edge of 

the dilled hole. You may have to trim 

the grommet to get an exact fit. 

(The flexible grommet is in the sealed 

parts package.)
