It's the exact same as the cover I have which is old and chewed on by squirrels.
"After looking up the wiring diagrams I was able to cut two wires which isolated the starter and ballast and rewired the lamp holder and I was done. It took me longer to find and shut off the correct breakers than it took me to wire 4 fixtures. The bonus was, I didn't have to remove the fixtures to do the work. I highly recommend these fluorescent replacement LED lights."
