Adding an accessory

Where do I get the power from ?

I have a nav 4 which uses a power connector under the battery cover. I would like to add a CB radio and I want it to turn off when the ignition is off. Do I cut and splice at that connector, is there a connector that I can get to accomplish that without cutting into that harness or just use a new fuse block direct from battery?
Thanks

Get yourself a centech fusepanel and connect to that.

Get a centech relay to control power to the fuse pnael and you can control on and off function.

This link should help you get the trigger wire http://forums.bmwmoa.org/showthread.php?t=39180

Another alternative is the fuzeblock. It is small in size, has the relay built in and is super easy to wire.

Thanks. Those have a single relay controlling all the circuits. Some of my acc. I want to turn on without the key.
The CB power I want to control with the same power for the gps. I'll use that to control that one relay.

The Fuzelock has a relay that turns on only the circuits you want turned on. The panel is set up so that you can move the fuse for that circuit left or right to have it switched on with the relay or on all the time...but still fused.

I use the parking light circuit wire to turn on the relay for the switched circuits.

I see that on the fuzelock, now.

One of the main differences between the two items is that the Centech will handle up to 70A, where as the Fuzeblock will carry 30A.

you need to make a determination of how many "things" you want to add to the bike and be conginizant of the limit.

AND...if you check into it, the remaining capacity of your alternator for accessories is likely only 30 to 40 amps anyway.

I forgot to mention that the Fuzeblock has diode protection to prevent the back emf of the relay coil (when the relay is turned off) putting a voltage spike onto your bikes electrical system. A well done unit.

Forgot to mention that some use a switched lead (grn/blu) on the diagnostic plug to turn on a relay. I feel more comfortable with that if the relay coil has some diode protection against a back emf voltage spike. It's the same voltage spike that makes the "points and coil" ignition (Kettering Ignition) work back in the day.
