12 volt accessory wire

[Picklito]

Is there a good source for 12-v accessory power on the EFI bikes (09 TE450)? Obviously I could go right to the battery with a new fused wire, but I'd prefer something that's off when the key is off?

Convenient places to tap into in that mess behind the headlight or underneath?

Plan is for grip heaters and possibly GPS and/or cell power. Thanks.

WOW, you a mind reader or what, I was about to post the same question.

I ran a lead off the battery for my 35w helmet light that came with a fuse and I ran toggle for on and off. The newer efi husky's run bad when the battery gets low, so I'm really nervous with doing this.

same bike too, how weird.

City light, its a brown wire, it's the little headlight that comes on when the key is turned on, and it runs off the battery, no relay or anything.

Thanks guys. I found this lonesome plug, yellow and gray wires to it, +12v when you switch the key on!
I think it's begging for some work to do. Anybody recognize that style of plug? Right now it's just got a blank
connector on it. If I can find the other half I won't even have to cut into the harness.

On my 07 TE610, the city light runs the 5W clear lamp up front and the rear tail light which is 8 or more watts as I recall. Plus it is off a 5amp fuse. So running high loads like grip heaters may tax the fuse and the wire.

It is better to run a wire and fuse off the battery directly for high loads. If you need it switched, use a relay near the fuse. You can use the city light/tail light wire by tapping into it near the battery on the way to the tail light. Whe thekey comes on, the tail light powers up, the tapped power turns on your relay, battery flows to youor grip heaters and aftermarket headlight or whatever.

I do not have the 09 TE450 schematics, so gave the 610 as an example of what to look for on yours. Might be the same setup.

Hi i think this is for the map switch on the handelbar

I'd definitely recommend switched power to your grip heaters especially with an EFI bike. As you mentioned earlier, if the draw is too high on the battery you may encounter some issues with the system. I have no experience attempting that method personally. My dealer said most of his customers tap into the headlight circuit somewhere behind the light, which would give you switched power that is only on when the bike is running and would eliminate the possibility of accidentally leaving the heaters on after shutting off the bike and thus killing your battery.

The plug you discovered is indeed shown as the connector for the map switch. Here's a link to a good Husky site where you can download the 2010 owner's manual as they don't shown any for 2009's and view the schematics for your self.

I had no lights to tap into so......I tapped into my Fan circuit at its fuse block with a piggy back blade type fuse holder called an "add-a-circuit". It allows you to retain the original circuit's fuse and then add your own fuse for the circuit you are adding. BTW I'm using the Symatec dual element style grip heaters that don't use the big ceramic resistor. The instructions recommend a 4 or 5 amp fuse. Man it's nice to have the hands warm when everything else is not.

Those are the grip heaters I'm using (dual star). I've installed them on several dirt bikes, but now want them on the DS cruiser, too. They are superior to the ones with the external resistor.

Everything you all are suggesting is exactly what I'm thinking about - load on the EFI system, auto shut-off when the engine's off, etc. Great work, thanks! Add-a-fuse is a good idea. Can look into a convenient spot for that, too. Relay is a good idea, too.

OK - Map switch? If we're talking ignition mapping... I did not know the 09 EFI bikes had an option for selectable maps! There must be an add-on switch that just connects yellow to gray and induces the map change? I'll be darned... haven't seen that come up in discussion here. Guess I missed it. And I guess I can't use that as my power source!

I just wanted to chime in to say that I used my low beam circuit for an accessory power location for a Garmin GPS. Works pretty well.

The low beam or tail light wire is a good one, I have also used it as a switch wire for a relay to power high draw items like heated grips.

is this light your referring to, is it the clear licence plate light?
