How to wire taillights on any car. I bought the taillights for the wrong year BMW, and I made them fit on my e46. I have been running this setup for about 4 months now with absolutely no issues.

Tip:
If you think about a harness as just a piece of plastic that makes wires connecting easier, you can have the assurance that you can make your own just by hardwiring it.
It is what I do with stereos as well. Instead of spending the $20+ dollars for the piece of plastic that connects the stock stereo harness to an aftermarket, I just wire it myself. It is really easy if you use the method I did.
I couldn't find the wire decoder online, So i just used process of elimination.

I hope this helps.
Please make sure your connections are secure. Don't burn your car down. I am not responsible if you try this. It is not recommended whatsoever.
A BMW mechanic would throw up at this.
