Junction Box Connector A (deferred)
Connections to this connector will be described last!
For each sensor you install, you should test it immediately, right there and then, by checking the LCD display on your DATAPRO-45™ main unit. The display channels are substantially, but not completely, in the same order as the connectors on the junction box. As a result, this documentation takes you through the installation process in the same order as the corresponding sensor channels are displayed on the LCD. Otherwise, you would find yourself laboriously scrolling through all of the channels several times!
Junction Box Connector B
To connect the power supply, first turn off the electrical master kill switch and possibly disconnect the battery. Use standard 14–16 gauge automotive wire, black in color for the negative wire and red in color for the positive wire. Connect the black wire to a good chassis ground that is connected to the negative terminal of the battery via another wire, or connect directly to the negative terminal of the battery. Connect the red wire to fused power source that is connected to the positive battery terminal, after the master power cut-off switch. Connect the other end of each wire to the appropriate junction box plugs and positions.
