Wiper Relay Location

ok, in the current financial climate and rising fuel cost i decided to downsize my old car for an even older micra (1.0L Shape L Reg K11), and im now in the the process of ironing out the minor faults with it, one of which is that i dont have intermittent wiper function. after doing a bit of googling i found out the most likely cause is the relay. and according to everywhere i looked it was a little black box next to the wiper motor. so i got one from a scrap yard and got it back to the car and mine doesnt have one there :confused: ??? only two rubber gromits where the one i took off was located.....so where is mine??? please help
