Ignition switch question 77 GS400X

[Nougat]

77 GS400X, I need an ignition switch. The actual part number is 37110-31017, and it looks like this: http://www.ebay.com/itm/New-Main-Ign...-/290801115978

That's a lot of money for a very basic switch, so I started browsing through other switches. I discovered this: 37110-25318 which looks like this: http://www.ebay.com/itm/Suzuki-TS185...-/170856655467

Any ideas about what would be different about these two, and why I couldn't just save $60 and get the cheap aftermarket one? The only thing I can see is that the wires in the plastic harness may be in different positions (but that should be easily dealt with).

One possible (major) difference between the two switches:

The first one (the one for your 400) likely has a PARK position to lock the forks and turn on the tail light.
That requires some different-than-normal wiring due to the way the switch works internally.

The second one (for the TS185) might not have the PARK position, so the tail light wiring will be different.

If you don't mind doing some re-wiring, you can probably get it to work.

No fork lock on this. The X model just has a bracket holding the cylinder. I actually have a switch, but there's no key and the harness is chopped off. The only label on the bezel says "off."
