No, that is not the relay.
The eight way's body is about 2x4 inches and about 2 inches high. The eight terminals are one each for the four light bulbs involved, power in from left and right turn signal switch, brake switch power, and flashing power. While non-actuated, power from the brake switch is directly connected to the rear lamps. When power comes in from left or right turn signal switch, a solenoid breaks the normally closed circuit to the respective side rear lamp and makes the circuit from the flashing power to the respective side lamps, front and rear. The completion of this circuit also completes the circuit through the flasher unit and thus that side starts flashing. With current going through the flasher unit, the indicator light is energized.
The later design that use separate rear bulbs for turn signals has flashing power going through the turn signal switch where as described above the turn signal switch directs constant power to respective solenoid in the eight way relay.

Thanks Jim
I hope Eric hasn't bought the wrong part, SWT 108 costs 260$

I couldn't find it on the Mini Mania site. It was used on other vehicles.
