You could solder the wires together but you would be better off putting the plug connectors back on for future plugs.

The easiest way to tell you what color goes where is by looking at the plugs and matching up the wires that connect together. If you no longer have wires going into the plugs and are just dangling there then you'll need to either contact AEM or wait for someone else to chime in.

Im planning on putting a new stronger plug on it, the connectors both ripped off when the caught the ground.

why did the plugs get "ripped off" to begin with? they shouldn't contact the ground. You need to review your installation...

You could hard wire the sensor, but they are replaceable because they burn out, so you'll need to cut the wires when you put a new one in eventually (or somebody will). I'd just resolder the connectors back on, or get a new wire/harness that plugs into the back of the gauge, but no harm will come from hard wiring (other than it being a PITA later)

Found this -- "These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output. The wideband sensor is laboratory-calibrated at the Bosch factory, accurate to 0.1 AFR and never requires free-air calibration when used with an AEM wideband AFR controller." -- on this website: - http://www.aemelectronics.com/produ...ensors/bosch-lsu-4-2-o2-sensor-with-connector

I checked a couple other models and it seems that most of them (if not all) are made this way. It doesn't sound like it's the best idea to solder the wires together. I agree with angelx; solder the wires back into the connector and plug. The last posting on this discussion was Oct 11, 2010, so I presume the original poster has it figured out; but I ran into almost the same problem, in that i forgot to disconnect the connector and plug when I was removing my downpipe. But hey... at least it's Friday![DOUBLEPOST=1408663695][/DOUBLEPOST]Also found a couple other links that might be helpful.

this link is for the white male plug, that plugs into the gauge
