trying to locate the pressure switch!!

I can see the pipe that leads from the steering pump followed this along but can't find no pressure switch can anyone help.
Yes this is not my engine bay but a pic I found that I could see the pipes as camera has not battery.

Its on the high pressure hard line just after the pump.

As above, you cant really miss it. It doesnt look like a switch, just a electrical connector plugged into the pipe.
