2023 3rd gen trd pro rear diff lock

I purchased my trd pro a month or so I'm using the black ops anytime locker switch i noticed when I use it i hear a click when the button is pressed but that's it just a single click everytime i hit the button the factory rear lock button and dash led are disabled does that click mean it engaged or ?

 

You might call the MFG. I think I read somewhere the aftermarket over ride I was reading on, did not turn on the dash lights,,, but I am foggy on that info.

I imagine this dude either is a relay or has relays in it that are actuating when you press the button. You are probably hearing those.

 

The click sound when the switch is pressed is definitely coming down by the dif i guess the only way to know if my dif is locked is to test it on gravel or sand/snow
