Low coolant alarm. Which one?

Where have you put the unit itself John? I'm just about to embark on wiring this in.

Just behind the driver's side kick panel. It just fits snugly above my cruise control module.
I drilled a couple of 10mm holes in the plastic so the audible alarm can be well heard.
I used the LED earthing wire for a bright red LED in my centre console just to the left of the rear demister button.
Both work well, they sound and blink each time you start as a self test.
