The 370Z Weight Reduction Thread

[wstar]

On a more-serious note about the wiring: I did put a big chunk of the removed harness stuff from the front half of my car in a plastic trash bag and weigh it. My bag came out to 16 pounds. This was most of the removed wire itself + electric tape, some of the small plastic modules for the key sensors and TPMS sensor, some of the conduit. It includes all the wiring up there for things like keyfob sensors, tpms, interior lighting, mirror, everything in the doors, and the airbag system (but no actual parts other than those dinky tpms/key receivers, just wire+tape+conduit and a few whole plastic wire-to-wire connectors where I wasn't using any circuits running through them). Doesn't include the stuff from the rear hatch area that I had unwired months ago and tossed.

It's probably closer to 20 lbs since I left out some conduit and threw away some things before I started saving them to weight later, but on the other hand I'll be putting back a little bit of tape and conduit, too, so 16 lbs might be a decent approximation of a net figure for the wiring conversion in the front. I could roughly guestimate that the rear half would've been more like 8 lbs (again just for wire/tape).

Worth it for the time investment for weight alone? Hell no, it's hard work. But if you're disconnecting all those accessories and circuits anyways, it's nice to have the car cleaner and simpler, and make it easier to diagnose other issues, etc. Most of the harness runs just get thinner, but notably at this level of stripping accessory circuits, the *entire* harnesses that run down the outer passenger edge and down the center console from front to rear get removed. Those all run needless accessory stuff. The necessary stuff in the rear (tail lights and a couple little circuits to the diff area and the evap canister) all run through the wiring harness on the outer edge of the driver's side.
