Hello Fellas,

Been a while since I've been on here, unfortunately me and "Siborg" are having some issues with 02 sensors not reading. Both of us have recently purchased a "Rywire Milspec Harness" After install we both get the same problem. No 02 reading on Hondata K Pro, we plugged in a scanner and got the code "1166" as well. 2 different cars, Motors, Same problem... Any ideas or help? We pinpoint its obviously the harness but before we take them out thought id ask here for any last opinions that may benefit us to try.
