Hi guys, I need some help on re-connecting the battery

! While I was connecting the battery I realized there is one wire that I do not know where to plug to (See Picture)

It looks like it's connected to a jack at the back of the stoplight.

yeah, i think it is connected to a plug toward the back. Not my photo but you can see the wire is routed to the back. GL.

Went to my car but I can't a place that I could plug it in!

maybe that wire is not suppose to plug into anything. There are wires that they use during transporting the vehicle. I will check on it when I get home and if i remember to do so.

I noticed that same wire when I was working on my system. I dont think its suppose to connect to anything. Hope Im not wrong because mines been unplugged since I got my car.

Do you have PDC ?

I think its the PDC power wire, and if you dont have pdc, it just sits there

txusa03 · 06-06-2007, 06:08 PM

As indicated I was going to check this out. It was not much to pull off the panel and look. I too have a 330i e90 and as far as I can tell, that wire on my car is not connected to anything. I am not sure what options you have on your car so this is all I can say. Hope that helps.

that wire connects to a battery disconnect switch that was used for transportation of the vehicle between the factory and dealership. The disconnect switch is removed when the vehicle is preped at the dealership.
there is nothing for you to worry about as the wire isnt used once the vehicle is in your hands. it doesnt connect anywhere. actually, if you wanted to find the other end, just pop up youre rear seat bottom, and look on the right side....
but again, that wire goes nowhere....

Thanks for helping out guys...... so I guess I do not have to worry since the wire has no use.

THANKS ALOT GUYS

^ and next time when you take apart your car, remember where everything goes! or take pictures

its for the transport mode battery switch. if you look under the right of your rear seats... there will be another connector that isn't being used.
