I had my bung and O2 sensor installed in the approved position last night.

I've pulled the wire up into the top of the engine ay but am just wondering where people have found best to get it through the firewall and into the passenger compartment.

The control unti is mounted under the glovebox on the LHS (this is a RHD car).

Any suggestions would be much appreciated.

 

I routed my WBO2 harness under the relay box near the fire wall. If you loosen the two bolts that secure the box and lift it up, you'll see the box sits over a large opening into the passenger compartment. I'm guessing you should be able to do the same in your RHD car, even though mine is LHD.

 

I pushed mine through the area that the wiring comes through by the battery, well just below by the engine.

 

Sincerest thanks for the help guys. I've just come back from the workshop... I managed to find a large rubber grommet on the passenger side of the transmission tunnel (should I say torque tube tunnel?) just by where the metal frame for the DME & KLR is - ideal position - I managed (just!) to get the connector through.

No I just have to work out why it's running so lean!
