Willie MacLeod Posted January 6, 2013 Share Posted January 6, 2013 The brown one (easiest to access) which has two wire connection on it, the single wire blue sensor is for the guage. Quote Link to comment Share on other sites More sharing options...
rodders Posted January 10, 2013 Share Posted January 10, 2013 this might help with my problem (misfire when hot) could someone tell me where the brown one is? Quote Link to comment Share on other sites More sharing options...
