http://www.o2sim.com säljer en sort, billigt
Info om hur den ska va kopplad finns här.
Just checked my connection,mine are the only working and tested nearly 5000Km without cel light come on !!!
Attach the RED O2sim +12V to the EXTERNAL white heater,all spliced togheter,Black O2sim ground to chassis,white O2sim signal to black lambda,leave the lambda signal alone wrapped with tape.
If you attach the +12V to the inner white,when the engine is running the voltages drop below 6V ........ and after +- 100km mil came on again!!
Där finns även lite info om hur man inte ska koppla den (typ som jag gjort innan )
