Looking for F3 Accessory switched circuit, found these wires - oops!

[adipaola]

I am trying to hard wire a GPS to my 2015 F3-S.
The wiring under the left cover has what looks like the switched accessory circuit I've seen in videos.
However, it is not labeled as such. This is the tag on the bundle I found:

Notice REV 00 November 26 2014. This is an early F3.

I removed one inch of the black cloth tape and there are 2 wires only slightly bare on the ends.
The wires are not connected to anything.
I cannot tell what color they are, they both look black, but it was dark and I need to check again with a brighter light.

In any case, I put a circuit tester on them with ignition on.
Instead of getting a voltage reading I heard a whirring noise when both probes made contact. Yikes.
I taped them off and the bike started, so I hope I didn't fry anything with that whirring noise.


Can anyone tell me if this is indeed a switched accessory circuit?
Any clue what the hell the whirring was?
I realize I have to test for 12+ volts ignition on, but I am paranoid now.
Any advice appreciated.

Thank you in Advance.
