Nath, i had the same problem when i did mine. Like they say, the terminals have a 'spade' fitting on the end right? If you just tape them up. they can short out within that spade fitting and 'pop' goes the fuse...taillight dont go then either.
i put the bulbs back in and tucked the whole lot in the back of the housing.It does get a bit tight in there for room tho.
If you desire, you could wire some blue leds into that park light fitting and have them under the fuel tank or somewhere. Then at night when you park the bike, turn the parklights on and 'WALAH!!"..you got blue lights shining down..i have seen that on a BigDog chopper at a bbq and it looked pretty cool...
