Just when I thought I had it all figured out you post something like this...now I'm back to being confused
I give up
Normally Closed (NC) switches do nothing more than interrupt the flow of electricity by breaking the connections. A Normally Open (NO) switch has an open connection and when you pull the spoon it grounds out a positive(hot) wire.
So for the LTR if you have a Normally Closed (NC) switch you want to do as I stated above and cut the orange wire with white trace and connect one wire from the switch to each of the wires you just cut. If it happens to be a Gunner switch you will also have a ground wire. Gunner has something going on where the ground is required. I haven't figured it out yet but it has to be hooked up to work properly when you hook it to the orange wire with white trace.
I haven't even researched a NO switch so I can't say for sure which wires you need to cut. Personally I like the NC switches because you are not grounding anything to kill the bike but to each his own.
Here's how I explained it on another site:
Just to clarify the difference between a normally open and a normally closed switch.
With a normally open kill switch you tap into the coil wire without breaking the wire and what happens is that when you pull the lanyard out it grounds out the coil.
With a normally closed kill switch you tap into a 12v line that feeds the electrical system by cutting the wire in two (which breaks the flow of electricity) and connecting two different wires to each end which go into the kill switch and when you pull the lanyard out it just breaks the flow of electricity.
Some may say "So What". Well if you ground out a Coil you run the risk of damaging your electrical system. I know Dyna recommends against the normally open kill switches in their instructions.
