LEAVE THE PLASTIC CONNECTOR COVER IN PLACE ( black square in middle of timer ) To connect your adjustable livewell timer into your current boat you will need to buy some 16 gauge wire, I recommend buying 3 different colors. One for power (red), one for ground (black), and one for the pump (brown). If these colors are not available, you can substitute another color as long as you can keep them straight. Marine wire is best as it prevents moisture from wicking up inside the insulation and rusting out the wire. In its place, you can buy regular automotive wire and I suggest soldering the ends to make a good connection. If the ends are not soldered, you should use electric bulb grease available at auto parts stores, or plasti-dip / liquid tape to seal connections, to prevent a bad connection that will happen over years of use due to oxidation, and the Automatic shutoff battery monitoring circuit will not operate properly. Menards, Home Depot, Sears, Wal-Mart, Gander Mountain, and Cabelas carry colored 16 gauge wire. You will also need some ¼ inch blue insulated, crimp, female, faston terminals also available at these stores, and a crimping wrench. WARNING: You need to connect the power wire to the fuse box in your boat, or buy a separate power fuse. Use a 5 to 6 Amp fuse to prevent damage to your boat or fires in case you’re your pump fails in a shorted condition, drawing large amounts of current from the battery and melting the wires connecting it to the switch and battery. The livewell timer comes with a temperature sensor already in it, and will automatically shut off if a shorted pump motor condition exists, but continued use of this sensor, to protect against a shorted pump for extended periods of time, may damage the sensor. WARNING: Take note of the GROUND terminal, it is the terminal that is facing the opposite direction of the other terminals. Make sure to connect the ground wire to the ground terminal (negative side) of the battery. If you connect the ground terminal to the power terminal by mistake, it is possible to damage the timer. You need to connect the output of the manual livewell switch, already in your boat, to the power input of the timer. If there is not a manual switch already in your boat, you will need to provide one. Typically there is already a switch in your boat, if not for the livewell, connect it to the auxiliary switch. The manual switch applies and removes power to your automatic timer, which then cycles between on and off as you have programmed by changing the potentiometer positions. Install the timer near the fuse box using 2 stainless steel screws (not provided). Mount the timer in a vertical fashion so it does not fill up with water and short your battery. The timer is sealed and impervious to water and moisture. WARNING: Do not install your timer near the fuel tank, or in an enclosed compartment such as in the engine compartment of an inboard motor boat. This is a dangerous situation and may produce a fire or explosion causing loss of property, personal injury, or death, in the event that the timer is installed improperly, or there is a fault in the wiring causing a spark, thus igniting gas fumes in the area. All Timers are tested and guaranteed to work properly and safely. Eng-Genius Technologies in not responsible for a fire or explosion causing loss of property, personal injury, or death, due to improper installation or improper use of the adjustable livewell timer. (for instance not using an inline fuse or connecting it to a 10 Amp load). Livewell pumps typically draw 2 to 5Amps.
And here is a picture of the installation in my boat, I mounted the livewell timer under the dashboard, and above where your feet go. It's in an area where you can still reach it if needed, but it is out of the way and next to my fuse box. The adjustable livewell timer was designed as a set it and forget it operation, meaning that you set the individual time settings and pretty much don't have to touch it again. You can see that I used a black wire for the ground which is connected to the ground terminal in the fuse box (the short copper bar on the bottom) I used a red wire to connect to the +12v of the battery which is connected to an inline fuse not shown in the drawing. (you can see the fuse box is full so I needed to use an external fuse) ALSO ( do not confuse the red wire at the top of the fuse box with the red wire on the timer) the red wire on the top of the fuse box is tied directly to the battery and is the power feed for the entire fuse box. The red wire on the automatic livewell timer goes up through the wire harness and gets connected to a manual switch mounted somewhere on your boats dashboard / instrument panel. At last, I used a white wire to connect the output of the timer to the livewell pump. The livewell pump in my boat has a black wire (gets tied to ground or - of battery) and a brown wire which is now tied to the white wire shown below. Also note there is no connection to the lower left hand terminal. This is the test terminal for the timer used in manufacturing, and should not be connected as seen in the installation picture below.
