Make sure you set your powersupply to North America mode!
Installing a PAL switch into all Amigas is always a good idea! You will want PAL mode for playing most games. But some games require NTSC or are just plain better in NTSC mode.
None of my A2000s had a simple jumper on the motherboard to toggle PAL/NTSC so I never had a PAL switch on those machines.
My A3000s had a jumper on the MB that allowed setting PAL/NTSC and it was dead ez to plug a switch with long wires onto that.
