so, i have been having no readings on the a/f gauge since the swap (if i put the gauge sensor wire into the OX diag box, i get nothing...if i remove it...i get a solid last green LED. Okay, so, i spliced the sensor wire right into the OX wire at the ECU. I still got nothing. later on, i noticed a wire that was not going anywhere (some wire I maid a long time ago) and I thought maybe that was the gauge's sensor wire and not the one i have been trying...so, i plug it into the OX in the diag box and the gauge starts to work! I figure...alrighty....i am on the ball....then i went ahead and cut the wire going to the ECU....i check the gauge again and it was solid green....so, i reconnected the ECU wire and it was going again....i let it run and bounce a while back and forth (the gauge led's) then I shut it off and taped everything up. I turned the car on again about 20 minutes later and i got nothing on the gauge again! blank! i cut the ECU wire again and got solid green. I connected that and tried everything i did before and all i got was nothing on the damn gauge....that is where i am...someone help me.
