Since there is no 4-pin connection, and a hard wire installation will be required, to perform a bench test prior to installation, here is a solution.
* Connect the light bar directly to the battery with the pigtail and mimic the signal in the interval between 0.3 secs to see if you are able to get the functions of the light bar to work.
Here is a video on how to test them directly from the battery:

- Middle Row: Reverse Lights
- Bottom Row: Brake/ Running Lights
