Verdad Gallardo i used # 66 cuz 65 was giving me shitty readings. . u just have to make sure that ur getting a good connection. . also u have to allow the 02 sensor to heat up take it around the block or for a ride. .it should bounce from lean to rich and go rich at full thottle .. . . . --LED lighting of just the readout, not the whole gauge. (Lean - Rich) Works with most OEM and aftermarket oxygen sensors, if sensor is needed--
Thanx a lot, finally got it, I used the #69 pin cuz I tried 65 and was weird , so this one seems to be working fine, thanx I tought people were not going to answer

The one that lights up, will have another wire you hook to a power source, you have just the read display Gauge, which will only light up the lean/rich LED's
