I just did a quick Google search for similar info and found the wiring harness for the Bentley Bentayga is 110lbs!

My point was, wiring harnesses are so much heavier than people think. Definitely something I didn't think about too much.

Sure, high end modern cars are out of control with all the sensors and electronics, etc, but there's a whole lot of wiring in these cars!!!

Most race preped e46 harnesses are 15-25 lbs lighter than stock (depending on what the car came with and retains)

That's why modern OEM's are driving for protocols like SENT - one wire, less copper less weight, less assembly... the list goes on

Harnesses were heavier before CAN BUS. The higher numbers also generally include the control modules.

I wouldnít doubt that wiring and control modules would be over a 100 lbs on a 7 series.

You can lose some weight in wiring. You can lose a lot in sheet metal and bolts. Thatís how race cars get below 2400. You can take a sawzall to the rear deck, doors, rear floor tub, and the battery box. Then drill out spot welds of all the unneeded brackets. Bolts...lots of bolts that arenít needed.

Just for reference I'm at 3068lbs with 1/4 tank of gas and no driver. The car is gutted no carpet, sunroof deleted, Kirk bar, still has A/C and OEM battery.

not accurate.

Every single wire associated with the harness (main harness, radio harness and battery cable) was in my picture that I previously posted. When I shipped that out, the package was 66lbs. Say a around 5 lbs for the plastic crate and you've got about 60lbs in wiring.

Vox how long did it take you to remove the full harness and can you share what the cost is to trim it down? I know there was a guy on the SpecE46 FB group offering something similar (you ship him harness and he'll trim it and ship back).
