Replacing ignition switch on 81 GS850G with aftermarket switch question

[Guest]

Has anyone replace the stock ignition switch with an aftermarket one?

the problem in question is most aftermarket switches I find seem to have a 3 terminals to connect to the wiring harness and the stock ignition has 4 wires coming out of it.

My wiring diagram sucks and is too small to read and I can't determine what the 4 wires on the stock harness power and if I can make a 3 position switch work for my application.

This is not the first time I've made modifications to a wiring harnesses but without being able to know whats what I'm stuck being able to make an educated decision on what I can make work.



So if you also have a readable wiring diagram that would be awesome.

Cheers!

Be careful - suzuki wiring is marginal

ignition wiring should be same as on yours, but headlight switch might be different- some models had on/off and sometimes switches get changed over the years.

Yeah the hand controls were pretty easy to figure out. But I just couldn't determine where the ignition switch started on my other diagram. Looking at it briefly it looks as if I can just eliminate the "park" option of the ignition.

Thanks again Tom

Rocketmann, did you ever figure out if the 3 terminal will work? I believe I'm having the same problem you are.

I doubt if anyone ever used it in the history of motorcycling.

Did you ever find out if those would work on your bike?

I purchased the Emgo brand ignition switch for my 1980 GS750E and it was plug and play. Looks and acts like original switch, everything works, no mods were necessary - 4 wires in and 4 wires out. Paid $21.50 US delivered on EBay on one of the links you have listed. Just make sure you get the switch that fits your year and model bike.

Bought this one last month. Plug and play. Amazon said it would not fit my 1983 GS1100G, but it works flawlessly.
