I did this a couple years ago and it was kinda tricky because there's very little info out there how to do this. I wanted it to be a clean and reversible install.

I highly recommend you don't splice the factory wiring. There's one company out there that makes a harness for our cars with the B&O system. Technic PNP. The pic I have attached is the harness you want. Well worth $50. I also hooked up an Lc2i and I highly recommend it. Passive LOCs are garbage.

Now you'll have a killer sound system that hits the bottom end.
