7 HARNESS WIRING AND INSTALLATION
Refer to the wiring schematic below (Figure 7) for making the required electrical connections:
CONNECT THE HARNESS TO THE BATTERY:
• Strip each wire end of the 30 Amp fuse holder, the end of the 10 AWG black wire, and the end of the 12 AWG red wire.
• Connect the 30 Amp fuse holder to the 12 AWG red wire by crimping the yellow 10-12 AWG butt connector to the wires.
After crimping, apply heat to the activate the heat shrink and seal the connection.
• Crimp one 10-12 AWG 3/8” ring terminal to each of the remaining wire ends on the 12 AWG red wire & 10 AWG black wire.
• Connect the ring terminals to their respective battery terminals as labelled, red to positive and black to negative.
• Insert the provided air compressor fuse into the 30 Amp fuse holder.
NOTE: If the negative battery terminal is not accessible, an external chassis ground may be used provided it has a clean
contact area
CONNECT THE HARNESS TO SWITCHED IGNITION POWER
Locate a source of 12 VDC switched ignition power within the engine bay. This power source will only be powered when the
key is in the ON position.
• Refer to vehicle wiring schematic, use a multimeter, or use a test lamp to identify an ignition power source
NOTE: A constant 12 VDC power source can be used, giving the user the ability to control their air springs while the vehicle
is off. However, the controller consumes 35-80 mA in standby mode, which will slowly discharge the battery.
