At the fuse relay center is the best place. do not go poking wires with your meter or test light on these cars. BMW major system operate via multi-colored optical cables that look very similar to standard wires.

fuse box is accessed thru glove box. good luck

should i use a relay and go directly to the battery, or is it ok just to tap in the fuse box

Anything with a purple primary colour is an ACC, look at ignition switch loom*, body control module or fusebox. Also in trunk area.
* If it's a plastic push key, trace the wiring down to the first module, there should be a purple ACC there.
