1993 1uz wiring harness weighs about twice as much as the 2uz used in a 2004 Tundra.
I think most of the weight and size difference is thanks to 1993 traction control and a diagnostic port on the engine (there are 2 total for the car)

Sc400 harness up front, 2uz harness out back, this is making me want to just use the 2uz harness since theres less useless wiring.(I’m going to tear both of them apart regardless because I need the 2uz’s coilpack connectors)
