Not sure how the wiper relay is involved with gauges Mark. It's a standalone system so not involved with dash. UR = Blue/red wire code, generic for headlight low beam
Edit: just checked wiring schematic and that UR110 wire as well as SR111 are high speed CANBUS low and high respectively connecting to immobiliser, BCU, ECU and of course dash which would be expected to drive instruments, immobiliser warning light etc. It appears the UR wiring code has been used for alternate purpose therefore but certainly not to wiper system - thankfully.
