2.2 Installation Procedures
When you install TREK-753, the first step is to connect the power and ignition cor-
rectly. TREK-753’s power cable is designed to connect to the battery directly. TREK-
753 can be switched ON/OFF both by the ignition signal or its power button.
2.2.1 Connecting the Power Cord
Connect the three pin waterproof power cord to the DC inlet of TREK-753. On the
open-wire end, one pin is reserved for positive voltage and is marked "+" which
needs to be connected to the power "+" side; one pin is reserved for ground and is
marked "-"; which needs to be connected to the power "-" side. And, one pin is
reserved for the ignition signal with an “ignition” mark. There's an independent
"Shield" pin in the power cable; please fix it to the O-ring which is beside the TREK-
753 power connector.
