wiring your GPS
Whats the best way to hardwire your GPS to the switched side of the electrical system, so it turns on when you turn the bike on? Garmin 276C...on a Yamaha XT250

Tap into switched power via a headlight or running light circuit.

Don't forget
and if you add a quick disconnet with two prongs, make sure the exposed prong on the supply side is the ground and NOT the power. :D Don't ask.

I'd add a relay which is triggered by the lighting circuit. That way if there is a "malfuntion" you don't lose your lights.

This is specifically how I do it. It is a little ugly and it might not be the best way, but has worked on bikes used for some really rough riding.

FInd a wire that is accessable and has switched power like one of those described above.

Find a convenient place and use an exacto knife to peel away about 3/4" of insulation. Strip back the insulation on the wire you are going to splice it. Wrap the bare wires together. Solder them. Wrap electrical tape around the splice.

I use a lot of those two-pronged SAE connectors. I create them by buying 12" two-conductor SAE extension cables at AutoZone and cutting the wire and getting two plugs to use. As the guy said it is really important that the positive wire be on the female side of the connector.

with a relay do I still need a inline fuse?

Fuses are always good to have. When using the relay the fuse should be in the load wire (controlled circuit) near the battery.

PosiTap connectors are handy for this type stuff.
