Hello, I though some one here might be able to give me some insight. What I am trying to do is make H4 headlights operate properly in a car that had 9005/9006's. Since the 9005/6 are single filament and they both come on when the high beams come on so I cant just cut and splice them to the H4 connector, otherwise both filaments in the H4 bulb will be on at the same time and the bulb burns out quicker. I'm just not sure about how many relays I need and how to hook up so the high beam triggers the relay/s to shut the low beam off. If you could post a pic of the relay setup or just what wires go where(30 ,86,87,87a etc) on the relay would be great. I know someone has done this. there are tons of sir front ended cars out there and all cant have screwed up headlights

Well heres what I was thinking tell me if I'm wrong. hook 85 up to the high beam power(spliced in, power will still go to the high filament as well) . hook 86 to the ground. splice 30 and 87a into the low beam wire( does this matter if its the power or ground wire?) and leave 87 blank. when the high beam is switched on it will cut the circuit from 87a to 87 and thus turning the low beam off right? does this make sense?
thanks all
