chazmink Posted April 26, 2007 Report Share Posted April 26, 2007 The Saab 9-5 radio harness does not have an illumination wire. The car has daytime running lights. Any suggestions on where to connect the D3 illumination line so that the day-night feature is functional would be appreciated. Thanks. Quote Link to post Share on other sites
cntrylvr79 Posted April 27, 2007 Report Share Posted April 27, 2007 Headlight switch. Quote Link to post Share on other sites
chazmink Posted April 27, 2007 Author Report Share Posted April 27, 2007 I appreciate the response, cntrylvr. That would probably work if I didn't leave the lights in the autosense mode. i imagine a photocell trips a relay somewhere but I don't have a decent wiring diagram for the car. I suppose I could start using the headlight switch but prefer not too. Amazing how lazy I've become. All three of our cars have automatic headlights. Thanks, again.

cntrylvr79 Posted April 27, 2007 Report Share Posted April 27, 2007 Sounds like you're beat. Unless you wire up a separate switch. Quote Link to post Share on other sites
chazmink Posted April 27, 2007 Author Report Share Posted April 27, 2007 I knew that was an option but was hoping to find an alternative. Thanks, again. Quote Link to post Share on other sites
cntrylvr79 Posted April 27, 2007 Report Share Posted April 27, 2007 What about tapping into the actual headlight wire itself. Then it'll only switch over when the headlights turn on. The down side is you'd have to run a wire from your headlight back into the car. Quote Link to post Share on other sites
chazmink Posted April 27, 2007 Author Report Share Posted April 27, 2007 That's not a bad idea. I'll have a look tomorrow, Quote Link to post Share on other sites
