2.
Find a suitable location to mount the relay on the battery side of the engine compartment.
Make sure the mounting location is not exposed to water spray, excessive heat, or moving parts.
3.
Attach both power supply wires (red) to the positive (+) battery terminal.
4.
Connect the ground wire (black) to the vehicle chassis or the negative (-) battery terminal,
connect the wiring to switch.
5.
Locate an unused grommet on the firewall. If one cannot be found, drill a ½” hole with no
obstructions on either side and away from moving parts and other wiring.
6.
Feed the switch connector through the firewall and into the vehicle interior to the switch
mounting location.
7.
Select a suitable mounting location for the switch such as the dashboard or center console.
8.
Clean and dry both the mounting surface and the back of the switch and use double sided
adhesive pad to secure.
9.
Plug the switch connector into the wiring harness and secure all loose wiring to ensure safe
vehicle operation.
10.
Feed the auxiliary light wiring to each light with the shorter length going to the light on the
battery side.
11.
Plug the power supply socket to each light and attach the ground wire (black) to the vehicle
chassis.
OPTIONAL LOW/HIGH BEAM CONNECTION
Some states require auxiliary lighting to be connected to low/high beam wiring so that they may only be
used when your headlights are on. An additional benefit is to prevent battery draining in case the
headlights are accidentally left on. If you choose not to do this you may connect directly to the positive
terminal and your auxiliary lights will operate at any time using the switch.
Feed the single (red) wire to the positive (+) low or high beam wire and attach using the blue
wiretap connector.
TURNING ON AND TESTING OPERATION
1.
Remove electrical tape from the negative (-) terminal and re-connect onto the battery.
2.
Turn on ignition switch and activate the auxiliary light switch.
NOTE:
If you attached the optional connector to the low or high beam you will need to turn on your
headlamps to that position before the auxiliary lamps will light.
If lamps do not light, check fuse(s) and all wiring connections.
Use wire ties to secure all loose wiring in the engine compartment, making sure all wiring is away from
moving parts and excessive heat.
CAUTION:
IT IS STRONGLY RECOMMENDED THAT ANTI-SEIZE BE USED ON ALL MOUNTING
HARDWARE.
