Welcome,

Oem Hid's Were a Popular Topic Back in The Day But Most Did Not Think They Were All That! A Bulb Upgrade Would Be a Much Easier Route. Anyhoo Here Is What We Did To Upgrade Back in The Day. I Don't Know The Exact Way You Turn Off the DRL But Here is Some Info Which Maybe Helpful!

Oh, Found A Forscan DRL Link See Botton Link!

See First PDF For Silver Horse Racing Wiring Cheat! UPGRADING TO HID!

I love the hid headlamp design .I don't have DLR I speak of the perimeter light when unlocking the car . I know HID cars don't have the headlamp on when pressing unlock but the Fog instead .

Oh, I Guess I Jumped The Gun. The Forscan Thread / Forum May Address That.

All The Info Posted May Help Shed Some Programming Light as it Were on Your Update.

I Don't Recall in The Silver Horse Upgrade Having To Do Any Programming Update.

Anyhoo, Checking Out The Info Should Be a Good Step in Your Upgrade Journey.

It's Been 18 Years Back When This Upgrade was First Done So I'm a Bit Rusty on the Whole Thing!

I'm Not Sure About What You are Not able To Access. Oh I Guess Actual Forscan Product Site.

I Just Went into This! Maybe it's Not The Site You are Speaking of But Might Be Useful!

Sorry, Trying To Help!

I Get it! I Was Thinking There Might Be an Existing Thread There With Some Overlap info Which Would Be Helpful. Would Be Nice To Post Though!

Well if Anybody With Some Real World Forscan Experience Can Help Our Friend Out Please Chime In!

Updated Title To Perhaps Draw In Someone With Real World Forscan Knowledge!

Bonne Chance!
