extra connectors in headlight?

There are two 'blind" wires inside the headlight. One is brown, the other is white/green. You can probably use them for accessories somehow. The brown one connects to the ignition switch and the rear tail light, the white/green one to the horn, turn signal and front and rear brake light circuits.

I am not sure, what the load of heated grips is. Personally, I would wire them separately with an appropriate size wire and fuse to the battery directly, maybe even with a relay to make sure you don't create a load issue and a cable melting somewhere else.

So the if brown is hot/power in your opinion would it be the best candidate for heated grips?

Eeeeeeeeeee, beware. That's a weeeeeee little wire, and inductive heaters draw a lot of current. That black wire leg that the brown wire taps off of powers pretty much everything but the starter on your bike, and you need to fuse it too. You would be wise to take power directly off of your battery, and tap the black/white wire to trigger a relay to power grips. Definitely switch and fuse it too.

...and I personally would not do this without one of the aftermarket alternators - are you running one of those?

Yes I have new alternator from Tim's so I plan to take advantage of the possibilities.

Alright then, you're good to go. It's the same circuit that you'd use to do a direct coil power project, pretty sure that's documented here. A plain old Bosch relay and socket will work perfectly, and although they are a bit bulky, spares can be had anywhere. Some of these come with 2 power outputs, so you could easily do the coil power modification at the same time from the same relay.

A number of manufacturers make relay-switched fuse blocks for exactly this type of application. They allow you to wire numerous accessories to switched or unswitched power. Here's an example:

OK I stared at that for a few minutes before I understood. What a slick, elegant design. Install the fuse in the right two terminals and the circuit is switched. Install it in the left two and it's unswitched. Great design.

I have a few of the Centech and they are nice, but this is nicer.

This was how I wired and mounted my coil power setup:

do you have that on your bike?

There is a whole thread about the benefits of feeding the coils 12v directly. On many bikes, 12v at the battery turns into <10v at the coils due to losses in the mile or so of wire it has to travel. If you followed the instructions for the Dyna coil wiring, you are OK. They can be fed with 12v directly as well.

I would run a fused circuit directly from the battery to power your accessories- doesn't have to be fancy.
