HI, I'm setting up water-tank float switch, and LED warning light on my dash to show me when water in washer-tank is running low, so I don't keep burning out those IC-spray pumps.
but I can't find how to get my wire through the firewall on my RS.

any tips please ?
thanks
Jon

there are these 2" diameter grommets in the firewall which you can remaove and punch a hole through so you can get the wire through. There is one almost in the middle of the car( behind the IC) and one under the Brake booster. you cannot see it from the engine bay, but can see it inside the footwell.(when you remove that felt insulation behind the clutch pedal)

thanks taiChih

I actually managed to do it, by taping my new wire to an existing wire with plenty of slack, then pulling it through.
I'll keep that in mind next time though, thanks
Jon
