ok, so i bought some IPF lights (Used), i tried wiring them with the harness and was only able to get one light working of 4, then i wired it like this; from the batter i connected it to a ATC fuse then from there i connected it to the switch, the switch has 2 prongs i grounded one and the other one is connected to the two lights.

Still only one light works, im not sure what to do from here? Ive checked all my connections and kind of between a rock and a hard place; if anyone wants to put in their two cents, youre more than welcome


Ive used the search but wasnt successful in finding what i need


EDIT: made it a little easier to understand

 

did you take a voltmeter to the wires into the lights to see if you are getting a +12V to them? Also try connecting wires directly from the battery with just a fuse and without any switch inline. I know the last time i turned them on all 4 worked. . . and ive never heard of lights going bad from NOT using them. If it turns out they are broken I'll pay for a new set. (I sold them to him)
