okay.. my a/f gauge stopped working on me.. i thought i just fried mine but after i got my turbo in i got my friends a/f gauge from him that worked.. i hooked up the red to the #1 ignition control on the ecu, purple to o2 on the ecu, and ground.. nothing.. i dont know what it is.. i have a good ground.. i know that cuz i'm grounding it to the same place my fields vtec controller is grounded too.. and i'm getting power cuz the power is spliced to where the fields is also hooked up.. nothing is working.. if it helps.. i did swap my vx to si.. ? it worked fine witht he vx motor...? what could it be?
