GHL lightbar 2

Does anyone here have these or are familiar with them? I want to use my own power supply for two reasons. 1 the PSU are 4 week back ordered, and 2 the largest one is 300W and I need over 400W. They use a 3 pin round connector and from what I can see online the PSU says pin 3 is un-used. But in the fixture it shows signal. I need to know if there is a jumper in the connector or if it is just positive to pin 1 and ground to pin 2 leaving pin 3 empty.
