    I bought a Ram Mount for my Garmin GPS and i also bought this Power Cord:

    I really don't have a clue on how to wire it to my 2005 VStar 1100. Anybody know the best way to wire this or point me in the right direction?

    Thanks

    It should be ok to wire it to any circut that is hot when the ignition is on. I don't believe the amp draw of thr NUVI would overload anything. I would try to avoid coil wires for fear of interference to the NUVI.
    If the chord was long enough, I would install a fuse link in it and go straight to the battery. That would be best. Good luck!

    If you want to power it all the time you can hook up it to running lights. They stay on all the time.

    Not necessarily.
    Mine are designed to run as long as I have the LOW BEAM on. The moment I go to HIGH BEAM, my running lights go out, then they return when I go back down to the LOW BEAM. Also, there is a "mini" switch hidden behind one of the running lights, in case I want to turn them off, and run just the headlight.

    You can always buy a 12 VDC cigarette lighter plug from a marine supply store. Some of their plugs are built pretty rugged. That way, when you get off of the bike, if you want to stow the GPS, you can just unplug it and go, instead of having to cut into the wiring to wire it direct. I haven't installed any sort of power supply for my GPS yet, but I do believe it can be done, without cutting into the wiring, and still have a clean look.

    You really made me look through wiring diagram. If it's stock the running lights are always on when the ignition is on. Unless you have them mistaken for passing lights. Those are addons and can be wired in different ways.

    I can't imagine why anyone would want to turn off the running lights, and run with just the headlight. I want all the cagers to see me, whether I'm coming or going, day or night. The more lights, the better.

    BTW, because I have the 3 headlights instead of the 1, I decided that I didn't want a headlight modulator. But I still want to install a Brake Light modulator.

    i'd go with wzdartan and go straight off the battery and the fuse option

    My choice would probably be to wire directly to the battery. You don't want to have to re-program your destination or any other settings every time you stop for fuel. Depending on what settings your GPS unit keeps and loses when it is powered off, this could become a real big pain in the backside.

    The cigarette lighter option would be a good choice. That way, you can add other things later (like a radar detector, mp3 player or cell phone charger) without any more wiring. Just make sure you put a fuse in the feed wire, and always put the fuse as close to the battery as possible (for the best protection against fire and equipment damage). You want to select a fuse for the weakest link in your circuit. In this case, it will probably be the CONNECTOR at the GPS unit. Even if you use a 10-gauge wire, you're not going to get 20 or 30 Amps to safefly flow through the power connector at the end of the wire. Even cigarette lighter sockets are usually rated for no more than 15 Amps, so the wire size should be selected based on the current rating of the connector. It doesn't hurt to use a larger wire, but you still need to fuse the circuit to protect any weaker components down the line (or install a smaller branch circuit fuse close to those components). The length of the wire is also a factor when selecting wire size, but it is almost negligible on a motorcycle because no single run is going to be more than a few feet.

    There are some variables that factor in but, to generalize (and be safe), use a 12-gauge wire off the battery and put a 15A (or smaller) fuse in to protect the wire. A 12-guage wire will actually deliver 20A, but this is no use to you if you have a connector at the end of that wire which will melt if anything more than 10 Amps pass through it.

    I guess I got a little off track. But we WERE discussing where to give the GPS it's power source. And my point was that using the running lights might not be the best idea, depending on your wiring setup.

    Hey,
    I'm not trying to argue with you, but want to make things clear. Maybe I'm wrong. I think that running lights are wired on all the time the ignition is on. These are 2 front amber [part of turn signals] and rear red [part of brake light]. This is a stock setup. I think what you referring to are passing lights [2 additional lights in front]. People wire those with low beam, high beam or with separate switch. I understand that stock setup can be changed and that's what you are trying to point out.
    Peace,

    I like the idea of having power to the GPS unit on regardless if the ignition is on or not. I just need to remember to unplug it when my ride is done.

    I also like the idea of having a fuse. I am assuming I can find something at the auto parts store, some sort of fuse block?

    And just to show you what a novice I am about wiring, I want to ask about the wire colors. Red can go to the positive on the battery terminal? And then the black goes where?

    Thanks to all.

    The black can go to the negative terminal of the battery, or any suitable grounding point on the frame. If you are going to remove your seat or tank, or both,look for any common grounds on the frame that you can "piggyback your new ground on to. That should work fine if you don't want to run a ground all of the way back to the battery.
    Make sure all of your connections are soldered and covered with heat shrink tubing. I hate crimp on connectors or "scotch loc" taps, they always cause problems down the road! Good luck!

    You're right. I was thinking of my passing lights.
    My mistake.

    I guess it doesn't matter. He is going with wzdartan on this one.

    I don't have a GPS unit or never used one before. Do they have to stay powered all the time? If not, you can wire small relay to turn the power outlet off, when the ignition is off.

    ...Do they have to stay powered all the time?...
    If you are asking, do they have to stay powered in order to remember where you want to go, I'd say yes. However, if you have your destination already programmed into the unit, it's simply a matter of turning it back on, and pushing a few buttons. Mine has a button that reads "Recent Destination".

    I got the same hook up from e-bay for 7 bucks. I put together a distribution block and relay so that power is on only when the key is on and wired the cord to the distribution block. There's enough room on the block to wire up at least 3 more accessories. Here's a link to the instructions if you'd like to try doing the same. all parts needed were bought at radio shack (20 bucks).

    I've thought about a relayed distribution block for the front of the bike also. That would be super handy for multiple accesories. It would be convenient to have it up front somewhere so you wouldn't have to go to the battery or fuse block every time you needed a power tap. Great idea and thanks for the link!

    Glad to help. I've got mine under my seat velcroed to the little tool tray. May move it to another spot later but right now it's in the most convienient place. Also got a plug hooked up to it where I can hook up a cigarette lighter type adapter to charge up the cell and ipod. The cigarette lighter adapter with about 2ft of cable can be unplugged for storage leaving a short pigtail hidden under the seat. brookshireinnovations.com/
    Oh yea, if you don't want to try making your own power block here's a link to some ready to install ones easternbeaver.com/Main/Products/Fuseboxes/fuseboxes.html
