If this wiring diagram is correct(?),then the 2 wiper relays look like standard 5 pin changeover types.They could be green relays plugged into the rubber type bases up on the bulkhead behind the fuse box.There does not appear to be a dedicated timer relay,perhaps it is controlled by the circuit in the windscreen sensor.
A closer look at the diagram shows these relays to be double output 2 x 87 pins.
