yeah not denying that, but me for one as i do 99% of my driving at night they were worth it, so far this year ive driven over 100,000 kms at night in the bc rockie mountains, not bad seeing as the average driver puts on about 25,000 kms, but to the op, when i wired my piaa driving lamps into my high beam, i unplugged the light to the connector and had someone in the car flick the high beams on and off while i poked the contacts with a multi meter, you want to do the same, but just have the drls on and see what you get and on which pin or look at this: http://www.4crawler.com/4x4/CheapTri.../H4_Pinout.jpg
