Should plug into your exhaust flow…so just follow your exhaust manifold down until you see it tapped in (wires protruding).

Don’t just splice the wire in your engine bay, thats ghetto. Find the corresponding signal input to your ECU and wire it near there. You can find this in the FSM wiring schematic.
