Thanks Alan ...for swift replay ! And sorry for still bothering .... when You have removed both original O2 sensors - how did You handle both "lost" sensor connectors incl. their cables ? Did You just leave them in place ? If so - do such signalless inputs to ECU not create error/failures ? Looking to G4X pin manual there is pin position 9 for sensor No.1 ( as You have informed ...) and pin position No.43 ... for O2 sensor No.2 ( postCat ) ... Can it just stay as it is ( with the lost signal from postCat sensor No.2 ?? Thanks again !

Hello Alan, ....coming back to Your 3 yrs old advice on how to connect the gauge/controller cables of the MTX-L device : what´s about the BROWN cable ( cable No.5 ) ? Did You reconnect it to the cable of the original O2 - sensor ? And did You You completely remove or disconnect the 2nd O2-sensor ( means the post-CAT ) ?? Would You pls. share such details ?? Thanks in advance_Lutz
