Mk2 retro fitted front fogs
 

Recently got my hands on a Mk2 ZR105. Doing this one up for my girlfriend for when she passes her test. The car has retro fitted front fog lights that don't work. They have been activated using the T4 but apparently there is a relay missing. All the ones in the engine bay seem to be there. Is there another one in the fuse box under the steering wheel or is it a BCU relay?
Cheers guys

3rd relay down on the right hand side of the in car fuse box

Thanks nice one!
