    Default All on high/low beams?

    Hi all
    I am interested in doing a all on hi/low beam light mod on a 1997 gmc sierra...does anyone have an idea about how to do this mod?.....i have heard of using a diode to link the 85 pin on the hi beam relay to the 85 pin on the low beam relay !!
    Any thoughts or opinions out there?
    Thanks

    Hope this doesn't get me in trouble, but it has been discussed at length over here:
