PLANNING THE INSTALL
THESE PLANNING STEPS WILL HELP YOU SAVE TIME AND WILL MAKE THE INSTALLATION EASIER.
DETERMINE THE MOUNTING LOCATION FOR THE AIR COMPRESSOR
- Provides ample air flow and is protected from airborne debris and moisture.
- Mount close enough to the ECU to allow Wire Harness connections to reach.
- If using the optional Firestone Air Accessory Mounting Kit, consider the
guidelines above, and follow the kit’s instructions.
DETERMINE THE MOUNTING LOCATION FOR THE ECU
- Mount close enough to the Air Compressor to allow Wire Harness
connections to reach.
- Allow room for Air Line Tubes to connect to the air fittings on the ECU.
- Allow room for the 14-pin ECU connector to connect to the ECU.
- Allow room for the Air Line Tube to run without sharp curves or bends.
- Using supplied fasteners shown in Step 3 is recommended. If no other mounting option is available,
see the sidebar on Step 2 for using the Large Nylon Ties.
- Select a location that is solid and secure on the body or frame of the vehicle, away from any moving parts,
electrical or any other lines.
PLAN INSTALLATION ROUTES FOR WIRING AND AIR LINES
- Make sure the Wire Harness and Air Line Tubes are not exposed to sharp metal edges that can damage them.
- Use supplied Thermal Sleeves on Air Line Tubes when routing near heat sources.
- Use supplied Nylon Ties to secure Air Line Tubes and Wire Harness to the vehicle.
- Make a loop in the Air Line Tube where shown. This creates a water/debris trap that protects the Air Compressor.
- Measure twice, cut once!
TAPE ALL ELECTRICAL CONNECTIONS
- Use electrical tape to appropriately secure and protect all electrical connections.
