I have an old 83 Honda express that I'm re doing. All the wiring was chopped up and the only thing I wanna keep is the ignition switch.

I found a couple places I can mount a toggle switch but not really a whole ignition switch. The scooter is too small.

The switch has four wires coming off of it, but only has an off/on capability.

The wires are, black, blk/white, red, and green.

Can this be reduced to just two wires; a power wire and ground? I wonder what the other wires are for? Lights?

Any direction would be helpful.

Thanks.

Moderator this maybe this should go into the "other bikes" section

Here is a link to the wiring diagram.. May be useful to some to help me out.

Looks like the Black wire goes to the lights and the Green wire goes to the Kill Switch, so all I would need to do is link one part the Black/White (Ignition) wire to one side of the switch for 'off' and the Red Wire (Battery) to other part the for 'on'???

Again there will be no lights nor kill switch on the bike. Nothing but on and off from the ignition for the battery.

Thanks for the help guys.

Judging from the wire diagram, without lights (including brake lights), you don't need the switch at all.

The key switch is switching the red wire to black when 'on'. The black wire is only feeding the horn and brake lights.

The 'off' position is connecting the ignition (black/white) to ground, cutting off the power to the ignition coils.
The kill switch ("Engine off switch") does the same, so if you keep it, you don't need the key switch. But then you'll always have to use the kill switch to stop the engine.
If you want to get rid of it as well, you can roll your own by connecting black/white and green to your toggle switch. The engine will stop if you switch it on

The kill switch has even been cut out before I got to the bike.
I thought the switch had to be turned to the on position to get fire to coils/battery. Turning the switch off kills the engine.

So if I understand you correctly all I do is connect green and blk/white wires together for the on position of the toggle switch. And nothing on the other post of the toggle? Or green on one post and blk/white on the other? I'm sorry I'm an electronic idiot! Haha.

Yes. Then you'll have to switch it off, in order to start the bike. In the "on" position, black/white will be connected to green and therefore the ignition coil is grounded and stop producing sparks.

Well I connected blk/white wire to one post and the green wire on the other and it worked like a charm. One way gave coil spark the other way didn't.

Thanks so much for your help.
