Oh yah the other thing I did to preserve my sanity was to cut the big wire harness they give into two pieces. I ran the part from the inside panel down and the part from the pump in and spliced together.
There are also some extra wires that go to the switch on each jack (detects if it's retracted all the way) and I did those separately too.
At some point I was trying to do the harness and wiring in one shot and that would have been really hard.
I also wish I had a hydraulic fitting press and that I could press my own hoses ... that would have taken a lot of planning and guess work out of what to put where and how to route hoses to make it all reach and not look like a complete rats nest.
