Power wire

I am installing my Zumo today and it will be installed on a factory base I am putting on. I want to wire it to a location that is only hot when the key is on. Where would the best location (not the map light) be for the power and the ground?

One good place to pick up switched power is the front seat heater plug, near the frame on the left side under the front of the seat. Be sure to attach to the bike side of the connector so the seat can be removed without disturbing the wire. There is a ground connection to the rear of the battery, or pick up ground on just about any brown wire. Do not ground to the frame, as BMW runs independent grounds to everything, and the frame is not used for ground.

On the BMW, never ground to the frame. Always find a wired ground, as BMW runs brown ground wires to everything (brown wires), not using the frame for ground.

Bosch color code (as I remember it) any black wire or Black wire with color is Hot with ignition. Red is hot always. Brown is ground.

Power for Zumo on RT

After reading many threads on the subject, one summed it up http://bmwsporttouring.com/ubbthread...rue#Post861990. Saturday I went to Chicago BMW and bought the recommended BMW connector (Part #83300413585 ). Sunday I connected it first to the Garmin power cables and then plugged it into the available Canbus plug taped to the fork. Long story short, ta-da, it works.

For reference, the connector has three wires, numbered 1,2, & 3. As posted in previous threads:

1=Ground
2=Speed Pulse (No Idea! I just taped the end off so it wouldn't short.)
3=power

I tied all the extra wire in a nice bundle to the frame/fork below the dash with wire tie. Didn't have to remove any tupperware. Very easy. Love my zumo. Getting autocom installed at the rally and then I am done for this year...maybe.
