lol....so now I need to figure out if that sensor is caput or....all that gauge cluster swapping in and out somehow screwed up my connections....

I suppose it's feasible that the sensor fried when I accidentally shorted out my old cluster with the tach lead....oops.

 

I'ma be honest....I'm not entirely sure what I'm supposed to do with that diagram.

 

If your speedo works then the rear axle sensor should be fine ... I would clear the code and see if it comes back, if it does you might clean the cluster connectors.

 

Update:

cleared the code. Code came back. It must be somewhere between the cluster and ECU. I checked the harnesses under the glove box and the plug to the ECU...haven't gotten around to taking the cluster out to clean those connections. I'll get there.
