I think you are right. I have a 9006/D2S harness and a 880 harness. I will dig the parts out of the box tonight and send you a PM on what I find.Mounce said:I might possibly have a 9006 relay harness that I can use it for the fogs if the plugs were compatible. Fogs will get 880 HIDs if they get them. I feel like they are compatible since the HID ballasts have 9006/5 looking connectors and the 880 wire will plug into them.
