I used speaker wire and so far it is good, time will tell. The good thing is, if it causes issues out on the road, it is easy to just pull the plugs and put it back to stock. I routed mine behind then over the fuel injection unit then along the hose that runs along the left side of the fuel tank so it's not subjected to very much heat. For additional protection, I covered the entire length of the wire in 2 layers of heat shrink tube.
