I pulled the relay board down but have no clue which relay does what- here is a pic of what I found- which one is the fog light relay? thanksClick to view attachment

What year is your 914?

I think it's the one on the end. Look for one with a white/blue wire.

The 2nd one from the left is the high/low beam and the 3rd one from the left is the flasher relay. Not sure about the others.

I think it's the far right relay.

'70-'71 914-4 and 914-6: Black wire w/ blue stripe will be plugged into the #58b terminal on the headlight switch, along with a grey wire.
'72-'73: Black wire w/ blue stripe will be plugged into the #56 terminal on the headlight switch, along with a grey wire and a red w/white striped wire.
'74-'76: Black wire w/ blue stripe will be plugged into the #56 terminal on the headlight switch, along with a red w/white striped wire.
