I'm trying to add a pair of factory fog lights to my '98 S70 GLT. I found that all the wiring appears to be there already. I got a pair of lights, the switch, and the relays (one of which is simply a jumper!) all from the same car at a salvage yard, connected everything, and... they don't work. What am I missing? does something need to be programmed? is there an additional part I need to get that I didn't see in the wiring diagram? Any help would be appreciated

 

Did you also get the headlight relay?

 

Ahh... different headlight relay. Of course. Okay... I'll go get that, too. Thanks!

 

Okay... got the headlight relay from the other car, swapped them out, and... they work! Thanks, Tech!

 

Glad all is good now.
