brakelight & indicator not working; bad connection

Hey all,

I have an 05 325i, and recently my rear driver side indicator and then my brake light stopped working. After some investigation I found my connector looking like this:

Is this a whole harness replace? Peice of a harnes?

Looks like something may have shorted...any tips on figuring out the issue?

Any suggestions on where to go from where would be helpful (other than "fix it"

Thanks for the help.

hey, that look pretty bad
I would contact Eurostyle get a new/used harness.
Before you do it however see if you don't have some obvious shorts.

Where the trunk closes there is a black harness which connects the wires to the trunk, cut that open and see if any wires are broken and proceed from there.

Needs more mods

Common failure on E46. That wire is the tail light ground. Cut the wire and discard the burned terminal.

Crimp new wire about 2'' to the wire you just cut. Get a spade terminal and crimp it to the new wire.

If you look closely at the tail light board you will see a spot near the bottom where the spade terminal can connect to.

Plug the connector back in and you should be good to go.

Cool. Thanks for the advice, i'll let you now what happens.

Just for kicks though, I went to BMW just to hear what they say and get numbers from them (always fun at the stealership). Here is a price quote they have me on fixing both taillights:
