OK let me get this straight... so the stock harness goes into the male connector (H).

Then the female connector goes back into the bulb? Am I correct?

Geez if this is correct then I'm awfully confused! Cause I was under the assumption that none of my factory wiring would be reused apart from the switches or something! Cause that factory wire is thin as, I think 18ga or something, wouldn't that affect the performance?
