H4 plug ?
 

I just got my new H4's and I am waiting for the H5 - H4 adapter from our host, but I was curious about the plug on the back of the new Bosch H4's there are 2 other connections that I am wondering what it is they connect to ...if anything. the new adapter connects the 3 prongs in the center to the H4 3 prongs.

sorry for the fuzzy pic ( I must have been too close )

I think you are referring to the connection for the little bulb above the H4. The lights are european and that is kind of a running light. You don't need to connect it but I'm going to run a wire from the parking lights to it.

(Hey! Maybe I can put a blue light in there so the ricer kids will give me some respect!) :p
