After wiring my plx with the dm-5 gauge, it just reads "rch" it does not give a a/f reading. This is my first time wiring a wb so im still a noob. it gives me the rch reading even before the oxygen sensor is connected, need some input. Thanks

The wiring should be pretty straightforward. You sure the wiring for the O2 sensor is all connected correctly? The only thing that is more difficult than a direct plug-in is the power and ground, which it sounds like you have done correctly.
