yes and no....

yes use those 2 pins...but DO NOT use a jumper... what u need is to just TEMPORARILY touch them and it should turn on.....usually a quick contact between the 2 pins would be sufficient. once its on there should be NO contact between those 2 pins

easier still and safest way....

since u have a case,,y not remove the switch from the case...plug it in and wala...can use just like normal

yeah lor.... can probably even get those parts in ace hardware oso

plus if u really pandai...some of the parts may not even require soldering....just straight crimp on the thing only
