used this on mine side cover on oil tank bottom ign. Switch small push button above is for starter others on top 1 horn one for hi low beam other and toggle for turns that's the extent of my controls for electrical on entire bike

 

I put mine on the battery cover; marine 2 way toggle, waterproof.

 

Dumb question but where'd you get that switch? Been googling for a minute and that's exactly what I'm looking for!

Also dumb question - if installing this as a kill-switch to my ignition (I already have a two-position push button ignition) is there an idiot's guide to wiring this in?

 

I don't remember where I got it from, it's been a few years, but I do remember that searching for "marine" switches is how I found it. As far as wiring it, there's 3 wires going into the ignition switch, on one pole I wired the hot and accessory together, and the ground on the other pole.

 

Here's one

 

Cool, that's the one I was looking at. So the switch doesn't have to be rated for a certain amp or voltage? Also, I am planning on using the switch as an interruptor to make it a secondary kill switch for my ignition...I just have to put it upstream of the ignition on ONE of the wires, correct? Is there any reason I couldn't put it on the ground wire? Seems safest to interrupt...

 

If you incorporate a relay, the amps that go thru the switch or near nothing. the relay contacts will handle the current. A cube relay like from a Chevy fuel pump relay.
Red feed from battery
Red/Grey accessory feed
Red/Black ign feed

 

I don't remember the numbers, but I looked up the amps involved in the ignition switch and determined that a relay wasn't needed.
