Can someone tell me the easiest way to find the 'low wiper fluid' warning signal (that lights up the annoying dash display and triggers the even more annoying warning sound)?

I want to "T" into the line.

What 'form' is the signal (I assume it comes in various form, from a sensor level signal at the reservoir (0-5V?) going to one of the modules (what module 'houses' the sensor signal processing? Convenience control module), and output signals to the dash display (I assume one pin of one of the connectors on the back of the instrument cluster), and another output to the noise maker.

Found some information:

Fluid level switch is F77

Does anyone of specs or details on the F77 switch? How many amps can I expect to run over the switch? Can it handle an additional (don't think the instrument cluster is drawing much over the switch) 700 mA?

Or better to splice a low amp relay to handle the extra load? If so: suggestions for relay?

Bump.
Even a guess or estimate would help.
Are we talking mA or couple of amps?
