Foglamp trouble

Took my 1989/90 K10 for the Mot today, failed on two items one being foglamp not working. I checked the bulb fuses and conections which are ok so it must be the relay, there are only three relays what I can see all on the right hand side of the car above the fuse box.
The blue relay is for the foglamp on the older car's, (left side) there is blue one on mine but the wiring on the back is the wrong size compared to the switch wiring?, any help appreciated.
