yes,what is the difference between 2 diagram above? my problem is my bike lamp H4 low beam can not turn on,while i see the the wire only 2 wire and not 3,while these 2 diagram one have and other have 3,any clue guys?
alright you looking at it wrong. in both diagrams the low beam shows only two wires. you are looking at the high beam when you see three wires coming back. if you trace the two wires one is obviously a ground and the other goes directly to your ignition which means its always on when you turn the key on. there is no way to cut it off unless you pull the fuse because it doesnt connect to the pass switch or the healight switch. have you checked the #2 fuse? if thats good ur headlight is blown
