Help ID'ing Hydraulic Steering Assist(?)

Alright folks - looking for some help figuring out this component under the hood. Hoping that the notated photos below will make it easier to understand than typing things out. Apologies if some of the labels I use for components are inaccurate... my auto-mechanic background is entirely self taught lol. Some text info first:
  • My van was originally built by an aftermarket up-fitter as a handicap van. As a result, there are a lot of bits and pieces that are non-standard compared to a factory van.
  • In preparing to install an aftermarket front bumper + winch (aka both have been sitting at my house for 6 months and I'm finally getting around to the project), I found something attached to the stock front bumper, basically right where a winch would sit. Only identifier on it is Monarch 08053 (which appears a 12v pump for hydraulics). My first thought was that it was leftover from the wheelchair lift that was installed on the passenger side.
  • BUT after tracing the lines coming from it, it now seems to be tied into the steering system. My best guess is that it is some sort of auxiliary power steering booster that was installed to make steering easier for the handicap conversion (ever since I purchased it, the steering wheel had an indentation on it from one of those steering wheel assistive knobs that allows you to turn the wheel with one hand).
  • My question is this - is my guess correct and can the system be removed? I'm guessing that in the stock steering setup, the power steering fluid line goes directly from the power steering pump to the steering gear assembly. As a result, I could run a new line between those and a new line between the power steering fluid reservoir and the power steering pump and effectively return the steering setup to stock and remove the auxiliary equipment. I may, to test the impact of doing this, remove the positive/negative leads from the Monarch pump and try driving it to see if there is a noticeable difference.
