it is on a 500,I will see if i can find where I got it. The little red button on my headlight bucket is the starter switch. When I put the new low and extra wide bars on (sorta like a 60's triumph) I put the coil power(on/off) , the headlight low/high/off, and the push starter button in the headlight bucket to clean up the bars(and eliminated the tunsignals and horn). The aftermarket tach only had one idiot light gel, so I made it the oil pressure light. Here are a few pics.......,
cheers...
