I know this because I pulled and labeled the entire harness from my 08 e92 (with most of the options including sunroof, drive) except DCT. That’s from the rear taillights, through the firewall to headlights but not including the underside battery cable.
I sent this to Germany and the 24”x24”x24” box weighed in at 62lbs. Had Martyn from Project Rogue thin it down retaining only the driveline and light components necessary. Don’t have an updated weight but will share once I do.
This means a significant portion of the 40-50lb weight savings you see posted with harness thinning is the modules, plastic brackets, metal brackets, etc. It’s not just a jumble of wires…

Thanks for sharing, I have a lot of low hanging fruit left to pull (airbag module, curtain airbags, entire headliner for that matter, AC is tempting with it's forward location too) and figured this would be a good place for knowledge sharing since it's such a rare project and the businesses building E9x racecars obviously aren't going to share everything publicly.
I wonder if there's much benefit moving the battery into the passenger rear footwell area to shorten the massive 12v wire.
I'll likely focus on the driver side loom that runs to the amp/Bluetooth module once I've pulled the modules/headliner & lower hanging fruit
