Hopefully the sensor is still useable but it may need replaced. You may have to replace the entire throttle body as Honda only sells new TPS that's way, but I've heard of people using a dremel on the studs and remove the sensor and replacing it. Takes a little work to get it perfect though.

Not sure what the plug you had was for? Need to check everything a little closer but it might be capped off? Nice on the LSD tranny. Did you get new axles too?
