I bought my 99' Max some fog lights. Found the relay and fuse. But, my Max doesn't come with the stalk or fogs pre-wired already. Im guessing I have to find myself some wiring harness to wire them properly. Any clues were to find this? Wires with the appropriate connections? Im guessing that Im gonna have to install a separate on/switch wired to my car, any recommended places for finding that?

I haven't seen a Maxima yet that wasn't prewired for fogs. I would have to look but I might have a stalk with the fog switch.

all you need to do is find a used stalk. the plugs for the stalk, and for the fogs, are folded and taped back. but they are there waiting for you.
