Chrysler Dodge and Jeep Vehicles 1992 – 2003 Superlift Suspension System PDF Installation Instructions

Find a suitable location inside the cab to mount the TruSpeed module. The module is water resistant, but it should be installed away from high heat sources such as the heating ducts and vents. In most instances, it can easily be attached to the bottom of the dash using the supplied two-sided tape. Separate the red and black wires from the yellow and green wires on the TruSpeed module. Using the supplied ring terminal, route and attach the black wire from the module to a suitable ground. Trim the wire to length as necessary.

Locate the fuse block for the vehicle. Fuse block location can be found in the vehicle owner’s manual or service manual. Refer to chart A to identify an appropriate switched 12-volt source on the fuse block for your application. The circuit should be hot when the ignition switch is in both the “start” and “run” positions. Use the fuse puller tool (normally attached to the fuse block or the access door) to pull the fuse indicated in the chart out of the block and set aside. Turn the ignition switch to the “on” position. Using a test light or voltmeter, determine which side of the fuse terminal (where you just removed the fuse) is “hot,” or receiving 12 volts. Turn the ignition switch back to the “off” position. Slide the appropriate fuse tapper into the hot side of the circuit (two are provided with the module: one for standard blade-type fuses and one for mini-blade fuses used in most late-model vehicles) and replace the fuse.

Trim the red wire from the TruSpeed module as necessary, attach the supplied spade terminal, and connect it to the fuse tapper. LOCATING THE SPEED SENSOR (All Jeep and some Dodge vehicles)… The speed sensor is located on the tailhousing of the transmission (on two-wheel drives) or
transfer case (on four-wheel drives). The tailhousing is the last 8 to 10 inches of the transfer case where the rear driveshaft attaches. There should be a two- or three-wire plug visible on the sensor.

Release the plastic locking piece and pull the plug straight out of the sensor. Refer to chart “A” for the appropriate wire identification (color code) for the specific year and model of the vehicle. The color codes in the chart are listed with the primary color of the wire listed first and the stripe color (if any) listed second. For example, WHT/ORG is a white wire with an orange stripe. Locate the correct color-code wire on the speed sensor plug and unwrap it from the rest of the factory wire loom. The TruSpeed is connected in two different ways: For all Chrysler and Toyota applications, route the yellow and green wires from the TruSpeed module to the speed sensor plug at the transmission or transfer case. For late-model Ford and Dodge vehicles, locate the appropriate color-coded wire (indicated in the chart) in the main plug on the ABS module. The location of the ABS module can be found in the factory service manual. Disconnect the plug from the ABS module. Cut the proper color-coded wire and strip both ends of insulation. IMPORTANT: [Diagram 1] It is strongly recommended that all connections to the sensor wire are soldered. Use the following method: Slide the supplied heat shrink tubing over one of the wires to be connected. Crimp each connection using the supplied non-insulated terminals. Solder both wires to the terminal. After allowing the soldered connection to cool, slide the heat shrink tubing over the connection and use an appropriate heat source to shrink the tubing. Wrap the completed connection with electrical tape and place back in the factory wire loom. Connect the green wire from the TruSpeed to the wire end leading to the speed sensor or ABS plug. Connect the yellow wire from the TruSpeed to the end leading to the wire loom / computer. NOTE: Improperly connecting the yellow and green wires will prevent the unit from operating properly. If applicable, reconnect the plug to the ABS module.
