Hopefully this is of some help to late Sprint owners.
Had a mates brother who is an auto electrician over to look at electrics as i thought I had a short/bad fault.
I have wasted endless hours on this trying to work out what the relay marked ??? was for, latterly thinking it was for rear fog lights
Anyway, it transpires that this works on the negative circuit and is not wired like other relays. It basically controls the light on the dash for low pads/low fluid reservoir. Which was what I originally thought, but seemed incredibly unlikely/unusual.
Hopefully of help to someone

And to add to my sense of total Belwiderment/wonder it seems that pressing the black bauble on top of the fluid reservoir has extinguished the warning light. At last. Reset switch?
