removing the rack is a bit of work, I would just convert it
I didn't get any pics when I did mine, but there's 3 holes. The proper way to convert to manual is to connect the 2 outer holes in a loop and then on the center hole run a line to a fluid reservoir with a breather on top. You don't need to keep the reservoir topped off with fluid. You only need enough fluid in the system to keep the inside of the rack lubricated. Sometimes the fluid level will go up/down as you turn the wheel and that's what the reservoir is for, to hold the fluid if it gets too high so it doesn't gush out through the breather and make a mess in your bay.
There's a company that sells a kit for $70-80 I think, or you can piece together your own for a little bit less.
