Headlight relay wire color?

[FJR-Voltron]

I've been trying to verify that the green wire with a blue stripe, that is located underneath the tach, is good place to tap into switched power?

I have a set of heated grips that I want to tap into an already switched power source, and I've read that the headlight relay wire (green with blue stripe) is a good healthy source of higher-amped power.

I don't know what color the wire is, but I would be careful about how many additional amps you try to draw through an existing wire. You would be better off using the headlight wire, or one of the other switched wires, to energize a relay and have the heated grips get power though the relay.

For switched power, the solid blue wires running to either the front signals is on with key. Just inside either lower fairing, easy to run up to the top of the bike from there. Use that to energize a relay and run your own circuit from the battery through the relay to your grips.

Only difference between that and the headlight circuit is that the blue wire is switched with the key, the headlight circuit is not on until the engine is running. That would be the green/blue wire between the two headlight relays. again, use it to energize a separate ciruit, don't add the load of grip heaters to the existing headlight circuit.

Ok, I found the headlight relay wire and it's actually the blue wire with a green strip (not green with blue). I got my heated grips wired through successfully and from what I can tell are working great. Although, it is a little hard to tell if the heaters are working when it's a 110 degrees outside

Basically, the power doesn't turn on until the ignition is actually turned over (engine running). Thus it won't kill the battery if I inadvertently leave the ignition in the on position.

It will, however, overheat the headlight circuit and either blow the fuse or fry the wiring if you wired heaters directly through that wire without a relay.

Reviving this thread because I'm looking for a switched power wire to tap for my relay. It's kind of cold out to spend extra time looking what with the snow and all.

Can someone tell me if the blue wire mentioned by wfooshee is still the correct color on the Gen 3? Any other front of the bike wires (color?) that are good choices and easy to reach?

I know I need to buy a shop manual but haven't gotten around to it yet. Thanks for any suggestions.

I think wfooshee is referring to a GenI, which would also apply to a GenII. The GenIII is different, it has LED signal lights driven from the meter module, not suitable for a switched source.

Your best bet for a "front" switched supply is probably the feed to the glove-box power outlet, it's a brown/black feed (brown/white after its connector). For the rear, a blue/red wire that feeds the licence plate light and rear lights (blue after their connector).

Hmm. Mine looks like a black wire and a brown with yellowish green stripe. I'm guessing it will be the brown one.

Probably, i'm reading the colours from the diagram in the Hayne's manual, looks like Brown/white, but I'd buy any light tracer colour. You could also use the brown wire that goes to the glovebox solenoid.
