[E-mysterymachine]

Hi guys,

Need some help.My h4 headlight harness gone case, so got a replacement.problem is i forgot which is to which.the h4connecter has 3 wires.my bike wiring to h4 connecter has only 2wires.tried a few combinations but no avail.

 

I managed to get the low beam working but my high beam doesent work.no prob with the fuse.

Bike is on singlw h4 bulb60/55watt.

If i am not mistaken, there should be a common ground and 2 for the lamps in the H4 bulb.

i.e. 1 pin for ground, 1 pin for low beam and 1 pin for high beam.

If you connect the negative wire to the ground, the other wire to any other pin should light it up
