Wiring Steps

The wiring of the White Night unit is very simple and straightforward. Each unit has 3 wires that must be wired to your vehicle to make the unit operate. The red wire needs to be connected to a 12 volt source. The yellow wire needs to be connected to the back up light wire of the vehicle. The black wire needs to connected to ground.

The White Night Toggle Switch: On the back side of the White Night unit there is a 3 position toggle switch. In one position, the White Night unit will activate when your ignition switch is on and the vehicle is placed into reverse. This is the position the switch should be left in for normal operation. The center position is off. If you place the toggle switch in the opposite position the unit will come on even with the ignition switch off. This allows you to use the light for many uses such as hooking up a boat trailer, changing a flat tire, or setting up camp in the dark.

If your vehicle has either a 6 or 7 pin trailer wiring connector you can simplify your installation (see below.) These trailer wiring connectors have a 12 volt wire that you can use as your 12 volt power source. The 7 pin connector also has a back up light wire that you can use as your back up light wire source.

Below are examples of how to wire your White Night unit. Choose the one that will make your installation the easiest.

TYPICAL INSTALLATION

This installation is for vehicles which do not have a 6 or 7 pin trailer wiring connector.

1. Connect the red wire of the White Night harness to a constant 12 volt source that has a 10 amp capacity. In most cases it will be best to route the wire up the frame rail on the same side as the battery. Be sure and secure the wire with wire ties to protect the wire from exhaust heat and moving parts. You may either connect the wire to the positive side of the battery or to a terminal that is supplied by the battery. Most vehicles will have a terminal in the engine compartment that has a wire coming from the positive side of the battery.
2. Connect the black wire of the White Night harness to ground (a conductive point on the frame.)
3. Connect the yellow wire of the White Night harness to the back up light wire of the vehicle. The easiest place to find this wire is usually under the vehicle at the rear. Most vehicles will have a group of wires going from the drivers side to the passenger side covered in plastic conduit. Pull a small section of the wiring out of the plastic conduit. In most cases the back up light wire will be a green wire. Make sure the vehicle is in park and apply the emergency brake. Turn the ignition switch to the on position and place the transmission into reverse. DO NOT crank the vehicle. This will power up the back up light wire.You can now take a prick type tester and prick thru the wire covering with the point of the tester to locate the wire. When you locate the wire with power, put the vehicle into park and turn off the ignition switch. Test the wire again as there should not be any power with the transmission in park and the switch off. Using the wire splice supplied, splice the yellow wire of the White Night harness to the back up light wire of the vehicle. Using electrical tape, wrap the spliced area to protect from moisture. Place the wires back inside of the plastic conduit. In a few instances the rear lighting wiring may be routed on the inside of the vehicle. In these vehicles it is easiest to find the access panel for the rear lighting and test for the back up light wire at the wiring coming into the back up lamp. You can then make your connection here.
4. Test toggle switch for proper operation and leave toggle switch in the position where the unit is activated when the vehicle is placed into reverse.

INSTALLATION FOR VEHICLES WITH A 6 OR 7 PIN TRAILER WIRING CONNECTOR

1. Remove about 12 inches of the plastic conduit from the wires coming into the rear of your trailer wiring plug. About 8 inches or so from the trailer wiring plug, connect the red wire of the White Night wiring harness to the 12 volt wire of the trailer wiring ( this wire is usually red ) using the wire splice provided. If there is not a red wire use a prick tester to find the wire that has constant power.
2. Attach the black wire of the White Night harness to ground (a conductive point on the frame.)
3. On vehicles with a 6 pin trailer connector you will have to refer to the TYPICAL INSTALLATION instructions above for connection of the yellow wire of the White Night harness to the back up light wiring of the vehicle.
4. On vehicles with a 7 pin trailer connector you can connect the yellow wire of the White Night harness to the back up light wire of the harness going into the rear of the 7 pin trailer connector. This wire is usually light green on GM vehicles, black with a purple stripe on Ford vehicles, and purple with a black stripe on Dodge vehicles. Use the wire splice provided and splice in the same area as you did the 12 volt supply wire. NOTE: It is always a good idea to test wire correctness before making any splice.
5. Wrap spliced wires with electrical tape to seal out moisture and recover the wiring with the plastic conduit.
6. Test toggle switch for proper operation and leave toggle switch in the position where the unit is activated when the vehicle is placed into reverse.
