I've tried everything I can find

Yet another wtf thread.

I have a light bar and wire harness I got used. Harness looks a lot like the HF I have seen online.

From the harness toward the switch I have 3 wires, black, white, blue.

Black is attached to relay pin #86 and is grounded to the battery negative.
White is attached to relay pin #30 and is constant hot from battery positive.
Blue is attached to relay pin #85 and activates the relay with ground and given + 12vdc

the lightbar comes on when white and blue wire are connected.

I have tried using the white +12vdc constant, and a tap to the tail light fuse, no changes at all.

I would like to run it through a mictuning switch, but none of the posts or videos I have seen worked.
Below is what I have, connect the lines for me please.

 

thanks. I'll give it a shot before ordering a new switch
