I'm in the process of installing a Garmin, but in terms of hard wiring it in, I'm not sure which way to go about it.

Has anyone done this before? Did you power it via the main fuses under the seat, or the secondary fuses above the water cooler?

I planned on hooking it up to the fuse for the headlight, but that is in with the "secondary" fuses and to keep it clean and ground to the battery, I need to install under the seat. Is it OK to go off one of the main fuses? Have any other ideas on installation?

Thanks in advance!
