They give you multiple options, you can hook it into the fuses and you can also piggy back off the head-unit itself,
Theirs only 7 wires
One is power and ground and ACC
The other 4 are speaker wires to connect to the stock system.
Also if you have the B&O amp you can power it that way as well and the led. It's literally a one to one copy.
The led is powered either through the block connector they supply or if you use the B&O amp to power it.
I'll have a write up as soon as I connect it up.
