^You need to remove the black panel covering surrounding the relay assembly. It's held on by a bolt or two and several pry tabs. The fuses in the corner are a clip on piece that remove as well. It's tricky but look closely at it and you'll see all the tabs.
Once removed all the wires are bolted on with 10mm and 8mm bolts. Just undo one at a time or number everything in order.
Sorry, I only have a few rough pics when I had mine apart. You can see all the wires loose not connected.
