I'm about to drop the downpipe and need to disconnect the lambda sensor and I'm having difficulty following the wire, from a photo it appears the connector is at the end of the head. To access this do I need to remove the engine cover or is it possible to do it from the boot access, if so what do I remove here, airbox?. The cable is also attached to the engine near the downpipe is this a clip? or do I have to unbolt it (it's pretty dark down there0, is this the only clip?
I intend when I locate the connector on the head to attach a string to it so when I disconnect it and pull it through I can pull it back again following the same route. Will I have problems doing this ie will it get caught on anything or is this bit simple.
