Brake light flasher and wire

[pwostrel]

Hello all I'm going to install one of those brake light flashers and was wondering if anyone knows what wires are what? If I remember correct there is a brown one, black with white stripe, and black with white stripe! What I need to know is what wire is the lead from the brake? Any help would be great I can do almost anything, but when it comes to wire I seem to screw it up, just thought before I started a fellow rider could throw me a safety net!

multi-meter thats my tip.  with a multi-meter you cant go wrong and heat shrink wire connectors.

For future reference:

The WHITE wire with the black stripe goes to the brake switch. There are two such wires joined into one connection on the bike's side of the last clip. The BLACK wire with the white stripe is the ground (earth) connection. The brown wire is the running light.

I made a mini-harness (I'm being euphemistic and optimistic in calling what I made a harness) so that I didn't cut any existing wiring and can revert to stock in a flash (pun... heh...) in case I sell or worse, in case the flasher fails on the road.
