I have a 40w FSL MUSE and want to upgrade to a 80w tube. I know I will have to cut a hole in the side in order to make the tube fit. My question is with the stock wiring. My 40w power supply has 3 connection cables and the new 80w only has 2. How would I wore the additional plug? PICS show the difference and what they power supplies and the missing wires between the two.
