Had my 05 rx330 apart for 2 months doing all sorts of fun things. Got the last bit of it put back together tonight and low and behold, I have 2 harnesses that I cannot find mates for. They are on the right side of the compartment close to all the intake stuff. Right now I have them pulled to the top of the compartment but they are long enough to reach the lower part of the compartment as well. Notice they are taped together so wherever they go, they go close together.

Any ideas?

Don't have a rx330, but could those be speed sensors on top of tyranny

Update: turns out this is the knock sensor harness.

Oh man, can you get to them without removing the manifold.?

Nope lol. Live and learn I guess. Had to take the manifold off to reconnect the sensors.
