Ok so i went and bought the two 1n4004 diodes from radio shack thinking i was going to come home and do this mod. Well turns out the pictures and threads i was reading on here must show for newer trucks and mine was thus different than the pictures. Does anyone have a picture or diagram they could show me on where to run the diodes? Will this switch lows and highs on at the same time when the high beams are on? And one last thing I have a button next to my heat/ac controls that says AUX LAMPS and it doesnt do anything from what i got from it. i push the button in and a yellow light lights up but if i let off it the light goes out! :confused:

For the all on mod on an 02 you have to ground out the yellow wire that goes in th back of the bulb. I just cut mine and ground it to the inner fender. This takes care or high/low same time.
