Wiper relay location

Happy new year!
On my RHD S3, it’s where the fuses are, passenger side.

I am going to assume that your SII XJ12 is the same as my SII XJ6 in this
area.
The Repair Operations Manual (ROM) lists the following for Windshield Wiper
Motor Relay Remove and refit:

Disconnect Battery

Drop Passenger seat side dash casing per 76.46.11
76.46.11: Drivers Under Scuttle Casing
1. Unscrew locking ring securing speedometer trip to underscuttle
casing.
2. Rmove two screws securing casing and quarter panel to fascia
support
bracket.
3. Lower top of casing sufficient to allow access to rheostat.
4. Noting position detach leads from rheostat.
5. Withdraw under scuttle casing and quarter panel from car.

Release relay securing spring clip.

Pull relay unit from base connector block.
…
so I’m not positive which side it’s on but it appears to be close to the
outer lower corner of the dashboard above the footwell. The relay appears to be a
12 pin rectangular shaped relay and has a spring wire clip over the top to
retain it. P/N is listed as C38952.
