Car is a 98 S70 GLT without the factory foglights. The wiring for the lights is there at the bumper and for the switch behind the blank off plate. So, aside from the obvious foglight assemblies grilles, and foglight switch, what else would I need to pick up to add working factory foglights. I'm assuming just a headlight relay.

Thanks in advance

 

I guess you know the 98 is the last year with a bank of relays under the dash. Which is good. they used a relay, a real one, at the upper left corner of that array under the dash. I guess everything else is present. In the US, power comes off the main headlamp relay, and I it looks like they're all the same. As you know, this only has power on it when the headlights are ON and low beam.

The wiring diagram in this case shows USA as a variation on the "standard" diagram.

When I look at the wiring diagram, I see where there may be a jumper in there that accommodates variations in the light switch (not the relays) used in different countries, and I have seen this jumper on the 850's. It was mounted in a relay box but it didn't have a relay in it. I can't find in the diagram manual where this jumper is located. So I am mildly concerned about that might be missing.

 

That item 34/13 is what I am wondering about. I looked and couldn't find anything saying where it goes.

 

Hmmmm.
