CAUTION
Protective wire loom should be used to enclose and protect cabling routed outside the vehicle
passenger compartment.
3. The RFID Extension Cable must be routed from the AIM2™ module outside the passenger
compartment to the RFID Interface Module near the fuel tank filler neck. If possible use an
existing wire chase opening to route the RFID Extension Cable outside the passenger
compartment. As required, drill a hole large enough for the connector on the RFID Extension
Cable to fit through.
4. Either end of the RFID Extension Cable may be connected to the AIM2™ module. Plug one end
of the cable into one of the module’s two Tank Ring Ports (Figure 4-2).
5. Route the other end of the RFID Extension Cable from the AIM2™ module to the fuel tank filler
neck. Use protective wire loom for any cable routed outside the passenger compartment, and
install grommets to seal any drilled holes. Leave room to adjust slack, and loosely attach the loom
and cable to the vehicle with cable ties.
6. Place the Filler Neck Ring around the filler neck under the fuel tank cap.
CAUTION
Use caution when working around the fuel tank filler neck with power tools. Some fuels are easily
ignitable, and some tools may generate sparks.
7. Route the Filler Neck Ring cable down the filler neck. As required, drill an access hole for the
Filler Neck Ring connector to pass through the housing at the top of the filler neck where the fuel
tank cap is located. If an access hole was drilled, protect the cable with a grommet.
8. Attach the RFID Interface Module to the Filler Neck Ring cable and the RFID Extension Cable
and secure in place with cable ties. If these connections are not in a protected space, use a
product similar to 3M Scotch Rubber Mastic Tape (product number 2228) or equivalent to cover
and protect all exposed connections.
9. From the AIM2™ module mounting location pull the slack from the RFID Extension Cable. Coil
any slack, and secure out of the way of the vehicle operator and/or moving parts.
10. As required, repeat steps 3 through 9 for the second tank of a dual tank installation.
11. Pull all cable ties tight and clip off the tag ends of the ties.
12. Seal any drilled holes/grommets with silicon sealant.
13. Connect the OBD interface cable to the vehicle OBD connector and AIM2™ module OBD port
(Fig. 4-2). Secure the cable out of the way of the vehicle operator and/or any moving parts.
14. Proceed to AIM2™ Post Installation Tests.
Using A Vehicle Speed Sensor (Odometer) Input Only
CAUTION
• Do not install any AIM2™ components in close proximity to hot or moving vehicle parts.
• The AIM2™ module should be mounted out of harms way, but remain accessible for service and
troubleshooting.
• The brown Analog Speed Sensor Cable wire must be connected to a source providing a 4 to
42VDC source wakeup signal to the AIM2™ module. This source must drop off to 2 VDC or less
to permit the module to go to sleep.
