How to prep engine bay for swap

[FRpilot]

i already started pulling things out of my engine bay and getting ready for a swap. so far, i pulled out the air box, battery, radiator, fan shroud, fuel filter, ignition coil and power transister, canister near radiator,A.I.V, and unplugged most of the wires.

i have an 89 fastback. im thinking about pulling out the power steering canister. what else should i pull from the car? im leaving the windshield wiper motor in there, but there's another piece next to it that im clueless about.
