Hi,
Looked at Deeps thread as im also fitting lambda link to my99uk at present,wired red-swithched live,black-chassis earth and then green to o2 white wire from bottom blue plug and white to earth in plug.I only knew these wires as also have Apexi timer that shows afr readings and had to splice into these to get a reading.
Switched on and nothing apart from the green power light on link,let it run for a few minutes as the Apexi wont rear afr till slightly warm and still nothing.The pisser is the wires were soldered to ecu ones for better reading so have been un-sildered now.
The book says that the green wire MUST go to the engine blockas an earth so this has confused me even more as to were the green and white are to go.
Any help appreciated before the link goes for flying lessons
Regards
Gene

 

Connections are red is switched positive, black is power ground, green is sensor ground and white is sensor signal.

Connect the red power to one of the ecu power feeds, black to the lower ecu mounting stud, white to the ecu sensor wire and green also to the lower ecu mounting stud.

You have incorrectly connected the sensor signal and ground.

Should have no problems then.

 

Many thanks Bob,wired it up as stated and all seems to be ok,thatll teach me to follow other thread info.
I owe you a large one and if your works answering machine has a bumbling message on it about lambda links when you next listen,i apologise as it was me today on the edge of loosing with the wiring.
Once again thanks and happy new year.
