I've searched the forums but cant find my exact issues.
Just bought a 2002 Civic 108000 KM. Previous owner had no headlights at all and only way to get them to work was to run a dedicated ground for the red/white wire from each light,this got only low beams,and RH drl dim,LH good.Without this ground,no headlights at all. All other lights are fine,and switch connector is fine. This is the only electrical issue.

Thanks
