This one. It clamps directly to the air flow meter, just under the rubber hose connecting the AFM to the resonator on the non-turbo engines. It secures the harness that connects the fuel pump resistor and ignitor coil.
It's doing its job perfectly fine; I'm just being really, really OCD about this and want to get a new one just because.
Normally such clamps have four or five digits somewhere on the part itself that are the second half of the part number, but this one has absolutely nothing aside from the 13 that indicates the diameter of the wire harness it clamps in millimetres.
