compartment. As required, drill a hole large enough for the connector on the RFID Extension
Cable to fit through.
8. 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).
9. 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.
10. 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.
11. 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.
12. Attach the RFID Interface Module between 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.
13. 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.
14. As required, repeat steps 7 through 13 for the second tank of a dual tank installation.
15. Pull all cable ties tight and clip off the tag ends of the ties.
16. Seal any drilled holes/grommets with silicon sealant.
17. Connect the Analog Speed Sensor Cable to the AIM2™ module Power/Speed Sensor Port (Fig.
4-2).
18. Proceed to AIM2™ Post Installation Tests.
Using An Analog Chronometer Input
Installations for analog chronometer input may be made with or without an OBD connection. When
made with an OBD connection, AIM2™ module power is derived through an OBD cable. When made
without an OBD connection an Analog Speed Sensor cable must be installed to connect to vehicle
power.
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.
NOTE
• A chronometer need not be a physical device added to the vehicle/equipment to attain the
desired information. A chronometer input may be as simple as a power source which only is
powered under special circumstances. Engine runtime may be a power source which only
supplies power when the engine is running. PTO engage time may be a power source which only
supplies power when the PTO is engaged.
• The Analog Speed Sensor Cable and Analog Chronometer wires may be lengthened, as needed.
1. Select a mounting location for the AIM2™ module. Recommended locations are under the dash
or under the seat on the same side of the vehicle as the fuel tank’s filler neck. Consider the
distance to the required connections when selecting a mounting location. Mount the AIM2™
module in the selected location.
a. (With OBD) The OBD Diagnostic Pass-Thru Cable is 48 inches long and cannot be
extended. It must be connected between the AIM2™ module and the OBD connector. The
