1989 Kawasaki vulcan 1500 A

My kawasaki has 3 pins for the clutch switch. I don't want to bypass it but the new master cylinder i bought has a 2 prong switch.

Is there a way I can make it work without bypassing the wires? I am using an aftermarket master cylinder and the kawasaki switch doesn't fit on it at all.

Anyone have any ideas on anything i can make or buy?

There's no way to make it work right. If you try to splice the wires, you're going to end up with funky behavior like the neutral light coming on any time you pull the clutch lever.
Any possibility you can just replace the switch component with a three contact switch and leave the master alone? As mentioned in the other thread, the 750 uses a different system, so this isn't the place to get a definitive answer.

This would be a good question to ask on a Vulcan forum that caters to all Vulcans, not just the 750, which has a cable operated clutch

What I meant was, can you look at the physical thing you bought (part number not provided) and see if there's a microswitch in there that is easily removable. If there is, you could look online to see if there is another microswitch by the same manufacturer with the same form factor that has both "normally open" and "normally closed" terminals. I imagine you could pick one up for a couple bucks, but you have the only information about what physical thing you have in front of you, and google will be able to tell you the rest.

If you want an 'outside the box' solution, its possible you could wire in a relay between your clutch switch and the harness. T the harness power to the relay, hook your switch's output to the primary coil of the relay, and the relay's "normally open" and "normally closed" outputs to the two signal wires of vn1500's harness.
