Non-destructive install of 987 seats into a 986?

[Nickanator8]

Hey all, I've scoured this forum, Pelican parts, 101 projects for your Boxster, YouTube, Google, ChatGPT, eBay, reddit, and everywhere else I can think to look and I'm at a loss. I'm hoping the right person lurking around this sub might have the secrets to the riddle I seem to have written for myself.

I bought a rough and ropey 986 in 2023 and have been trying to spruce it up ever since. The original seats are cracked, torn, and missing foam in some places. Naturally, this seemed like a good place for an upgrade instead of a 1:1 replacement. I found some 987 seats for $688.25 that I would like to install in my Boxster, but they are far too tall as standard and need power to get to the correct height.

I've found a million-and-one tutorials that claim to be for this install process but all of them cover an ultra specific section of the install and assume you've already wired everything together.

I expect I will sell this car in a few years, as it's an auto and I'm craving a manual. Because of that I want to make sure any modifications I make are either reversible or add more value to the car than they are worth (impossible to do when the car has 162k on the clock). I know I got a screaming deal on the 987 seats so I'd probably pull them out when I sell the car and swap the old seats back in. This is why I need to not destroy the wiring harness, I need to be able to undo the work one day.

I'm completely lost here and hope someone here might be able to guide me in the right direction with this project.
