Re: Ignition wiring
To use the new switch, you're going to have to also buy a mating connector/terminals/seals like the OEM or hack up your main wiring harness (not a good idea). The OEM switch has a key actuated pin for the steering lock that I'm guessing your new one doesn't have. The OEM switch has a built in resistor for one of the leads to the ECM that your new one probably doesn't. The OEM switch has a Park position where only the turn signals and running lights work. I'm suspicious of that feature being in your new switch. So, all in all, you're probably better off returning it and getting the correct Suzuki part.
If I'm wrong and the new switch has these features, it should have come with a wiring diagram. Did it? I can't tell, does it have five or six leads?
