Installation Notes It is important that you complete all the installation steps before operating the system. Follow all safety precautions for underhood mechanical work. Use Loctite 242 or equivalent on all engine-mounted fasteners. All hoses, tubes and wires which are rerouted or shifted during installation must be secured so that they do not contact excessively hot areas or sharp edges. Where possible, follow the routing suggestions in this manual. These installation instructions are intended as a general guide. In some instances, due to variations in vehicle manufacture or if prior modifications have been made to the vehicle, it may be necessary to carry out grinding, bending or rearranging operations for correct fit. These operations must follow sound, standard shop practices. Left and right definitions in this manual are determined when sitting in the driver s seat, facing forward. All fasteners must be of the correct size and torqued according to specifications (Table 1). Torque specifications are in foot pounds (ft-lb) and are only applicable when Loctite is used. If the threads are dry, add 20% to the torque values.

1. Connect the two interface cable connectors. A wiring diagram is shown in figure 4.4. Tape up the yellow DDC wire and tie it up under the dash. 2. Connect the green wire with the ring connector to a good ground. 3. Route the red wire with the fuse holder under the dash to the fuse panel. Locate an empty fuse connection and install the red wire using the fuse holder connector. 4. Locate a fuse in the fuse panel that will provide power only when the ignition switch is in the ON position (Figure 4.5). Figure 4.5 5. Locate a grommet or other opening in the firewall and feed the white wire from the interface cable and the grey cable from the control panel, through to the engine compartment. Connect the white wire to the matching connector at the compressor clutch, and the grey cable to the temperature probe cable. 6. Leave the red wire under the dash near the throttle pedal for connection to the throttle control. 7. Replace the doorsill trim at the driver s door. 8. Replace the fuse panel cover. 42
4.3 Installing the throttle 1. Using the supplied nylon ties, mount the throttle up under the dash near the accelerator pedal. Keep the adjustment screws accessible. 2. Disconnect the OEM connector at the accelerator pedal position sensor, and connect it to the connector on the throttle. 3. Connect the black throttle connector to the accelerator pedal position sensor. 4. Route the red throttle wire to the red wire from the interface cable that was set aside in section 4.2, step 6. Connect these wires. 5. Connect the green Ground inch wire from the throttle to a good ground. 6. Route the grey Pressure sensor cable from the throttle through the firewall to the compressor, alongside the white Clutch wire and connect it to the pressure sensor on the inlet control valve. 7. Cover the wires in the engine compartment with the supplied split loom. 4.4 Hydraulic brakes 1. Locate the black and white park brake wires that route under the floor mat from the park brake and come up beside the accelerator pedal (Figure 4.6). Figure 4.6 43
4.4.1Hydraulic brakes and standard transmission Figure 4.7 1. Disconnect the OEM connector and reconnect it to the mating connectors on the Parking Brake black interface cable wire (Figure 4.7). 4.4.2Hydraulic brakes and automatic transmission 1. Connect the VR black wire on the Drive Disable Circuit. (DDC) to the black wire on the interface cable. 44 Figure 4.8
2. Disconnect the OEM connector and reconnect it to the mating connectors on the Parking brake black DDC wire (Figure 4.8). 3. Locate the connector shown in Figure 4.9. Figure 4.9 4. Locate the pink wire labeled L17E at pin G of the connector shown at the transmission (Figure 4.9). 5. Solder the blue DDC wire to the pink wire labeled L17E on pin G as shown in Appendix A. VMAC recommends that all wire connections be soldered for reliability. A T-Tap connector has been supplied if this is not practical. 4.5 Final testing and assembly 1. Block the wheels of the vehicle. Apply the park brake, and if it is an automatic, put the transmission in neutral. 2. With the battery reconnected, turn the ignition to the Run position. Do not start the engine. 3. Turn On the control panel. The green light should come On. 4. Release the park brake. The green light should go off. 5. Reapply the park brake. 6. If the truck is an automatic, shift into gear. The green light should go Off. 45
7. Shift back to Neutral. The green light should come back On. 8. Turn off the control panel. Shift the transmission into gear. 9. Turn on the control panel. The green light should not come On. 10. Shift back to Neutral. The green light should come On. 11. Turn off the control panel and ignition. 12. Secure the wires in place under the dash and make sure that none of the wires interfere with any moving parts. 46
Appendix A - Soldering Instructions 1. Cut the OEM wire, and strip approximately 1/2 inch (13 mm) from each end and from the VR70 wire (Figure A1). Figure A1 2. Slide the heat shrink provided onto one OEM wire and the VR wire. Twist the three wires together (Figure A2). Figure A2 3. Heat all three wires at the joint with a soldering gun/pen, then apply the provided solder. 47
Ensure the solder flows into the joint to bond the wires together (Figure A3). Document #1930036 Figure A3 4. Slide the heat shrink over the joint, and shrink onto the joint using a heat gun. Make sure the shrink is heated until the liner melts and makes a good seal (Figure A4). Figure A4 48
