powertrain control module on rs turbo. air/fuel on rs turbs
Hello there. I purchased a air/fuel gauge for my rs turbo and was told i needed a lamba sensor. I have one in the exhaust already as I got it from a turbo with cossie management.
However. The wires were cut and I assumed the gauge was wired to these, but apparantely not. The wires on the sensor should go to a PCM (power control module). What are these and where would one of these be located on an rs turbo. The gauge is to be wired there.
If it can be wired straight to sensor could anyone explain. MAny thanks

A PCMis only a fancy name for MAIN relay, that feeds ECU, fuel pump relay etc after switch on.
The important one is SIGNAL, which is the BLACK wire from the lamda sensor, then just as marked on guage earth, live(ignition), lights(if fitted).
Make sure ignition live is switched, ie only on with igntion in position 2, and off when key out.
