Block LED Lamp Installation

1. Remove light bar from packaging. Check to see if all parts from above table are included.

2. Place template that matches purchased light (located on last page of instructions, only one template will be use) (20" flush mount template not supplied) in location desired. (Recommend not mounting to material more the 1/2" thick)

3. Cut out center of template with saw or Dermel. (Before cutting verify there are not obstructions on opposite side of mounting location

4. Drill 3/16" holes in locations marked on template.

5. After hole is drilled, mount the flush mount block LED light through hole cut in Step 2. Bolt on Light by placing bolts through holes and insert washers and lock nuts on all the bolts. Tighten with 3/8" wrench and 5/32" hex wrench.


1. Remove wiring harness and switch from kit.

2. Route wiring harness so that the red and black power cables are routed to the battery, the three switch wires are routed to your desired switch location, and the Deutsch plug is routed to the light bar. Keep wiring away from anything that will get hot.

3. Mount relay with desired hardware in a position under hood or in cab that is limited to water exposure.

4. Plug male (on the wiring harness) and female (on light bar) Deutsch plug connectors together.

5. Drill ¾” hole in desired switch mounting location. Verify there will be enough clearance behind switch to plug in the wires. Notch a small slit in the side of the hole using a file. This will keep the switch from turning.

6. Press switch into hole; verify that the notch made in step 5 lines up with the notch on the switch.

7. Plug wires into switch. Prongs on switch will be marked 1 through 3. Red wire goes to prong 1, Blue wire goes to Prong 2, and the Black wire goes to prong 3 (gold prong).

8. Attach power cable to the battery. Red goes to positive and black goes to negative.
