Hi,
I have just bought some Hein-Gericke grips in their sale for 30 quid!
Obviously, i don't want to put it on the battery terminals in case i forget to turn them off and get a dead battery.

I was wondering if anyone else has wired it into a switchable 12v supply on the harness. I know on my friends hornet, he got it wired into the front light but i am worried that it may draw too much power from it and dim my lights as obviously the hornet has a different harness etc.

Was thinking of the wire for the horn as i don't tend to use it as a tt with an aftermarket stubby at 8k revs is much louder than the tiny little horn already installed.

any feedback would be appreciated, i just need to get around to bothering to fit them!

Tap into that stupid little marker light. Its right there in the open and if it draws too much power the only light it will affect is the marker.

Use a simple relay to supply switched power from the battery. You are right that you don't want to power direct from the battery as its too easy to leave them on and find the bike dead. And you don't wasn't that much load drawing on an existing circuit.

If you aren't familiar with wiring a relay you can find schematics on this forum. I think D'Cosse has posted some. It's pretty straight forward and the relay is cheap.

Just did a quick google for you on how to wire a relay. Here's a pretty good primer on how/why.

In the case of your bike, the switched source (terminal 86) could be pretty much anything that only has 12v with the key on. The relay draws so little power it won't matter. Headlight, running light, etc would all work.
