I haven't looked at the motor harness yet, but the harness from the haltech to the jumper board isn't using shielded wire where indicated. Stock BRZ harness from the jumper board to the engine bay connector may or may not be shielded too.
I corner weighted my car today, it went from 2901lb with the Harrop/FA20 to 2687lb after the swap. Ballpark it at about a 200lb weight loss.
