If there is a fuel leak, it could ignite from the accessory wire shorting on something.
The fuse panel is a much safer place to grab power in a BMW.
I doubt your certificiation went over that...
I should have clarified above, the proper way is to grab power from the distribution block on top of the battery and not directly from it.
You will need to buy the small connector and metal crimp peice that slides into if you still want the BST and IBS to be active and fully functioning.

Can you explain this in noob terms. I didnt even know about these sensors. I actually am drawing power for my rearview camera directly from the battery in the trunk. Is there a picture of the top distribution block? Now you got me all worried.
