I have an 02 viper, non-elec. start, no reverse. Do all vipers have three wires for hi/lo beam switch or do non elec. start have two. Mine just has two, but i was told they all have three wires. Could someone let me know. Thanks.
 

Your hi-low is operated via a relay. The two wire switch turns the relay on and off. The relay is what is actually switching power to the headlight.

Three wire switches are in a system without a relay and it is doing all the work of diverting power.

They must have increased the lighting power on later sleds and changed to the relay system. Relays will last longer under higher loads than switches which is probably why they changed things.

You need a two wire switch.

Don't know why you're changing it but if it's because the headlight isn't working you may have a relay issue and not a switch issue. A continuity test will verify the integrity of the switch. It should have continuity in one position and none in the other.

Thanks. I lost the original switch for it. I have a three wire switch, but can't find a two wire switch.
