No problem. Not all systems are plumbed like this though. Some have an extra fluid block next to the pump that acts like a lock when the canopy is lifted. Get a marine based pump, follow those schematics, and you'll have zero issues.
I had the pic below in my schematics folder. It’s not for the Sterling per se but it was a nice clean schematic used for a convertible top with an electro-hydraulic pump (which is analogous.) I kept it because it had a few good reminders…like to have both the switch circuit and the pump solenoid circuit be connected to an “always on” power source.
Oh, I remember the other thing I liked about it: It has an actual circuit breaker going to the pump. They use those a lot in home-built aircraft. Instead of a fuse that just irreversibly blows. It’s literally a little button-like circuit breaker that can be reset if it pops. I don’t have that in any of my current cars but I always thought it was a neat idea. (I have no idea why they used a circuit breaker AND a fusible link to the pump. Those seem totally redundant when used in series.)
