2009 Automatic headlight switch schematic?

[FireEscape09]

Looking for a schematic of the headlight switch. My specific need is to tie into the AUTO setting. I want to use the auto setting to trigger DRL's. That way if I actually have it set to off, the DRL's will be off too. This to me is way more functional than just tying the DRL's into the key-on circuit.

Why not just take it to the dealer and have them enable DRL's in the SJB?

That would use the headlights for DRL. I'm going to use LED's for DRL. So by tying into the AUTO function, I can use that to enable to LED's rather than plain only key-on.

Oh that is perfect! I was hoping that the headlight switch was ground switching. This makes my install very easy. The relay coil for the DRL LED's get's it's ground from the AUTO-On Circuit, and it's +12 from an ignition-on circuit under the hood. All the logic in one shot. With headlight switch in the off position, the DRL relay has no ground. And with the key off, the DRL relay has no +12. Perfect!! Which means they will never come on with the key off, and I can disable them entirely by switching the lights to OFF.

Very useful thread.. I bought some led lights for my car last month from the http://www.panaceaco.com .. I was looking for the schematic diagram for installation of these led lights.. This thread helped me to make it easy.. Thank you..

Any chance someone has those automatic headlight switch schematics? They seem to be gone.

Best I've got, I know it's too late but maybe help someone else.
