To the OP, follow the FAST instructions to the letter. I just installed a FAST EFI on my Bee, it works great. The only deviation I did was install a relay on the pink switched power wire. I installed the relay next to the battery so I could tap into clean battery power. I did this. Because research indicated a lot of guys needed to install a capasitor in the pink switched power wire to clean up the electrical noise/voltage spikes. The switched power controls the relay. FAST claims the MSD is one of the sources for electrical noise. Also install resistor plugs if you don't already have them.
