Where is it on a LS integra engine ?

 

On the transmission near the back.

 

Ill take a look

 

 

Yup Thanks what could cause my MPH gauge ad RPM to fail?

 

(speedometer, tachometer)

speedo, maybe from the vss, but your odometer (you might call that a 'miles traveled gauge' ) wouldnt work either
The tach, isnt dealing with the vss at all

I say, check your cluster connections and fuses before wanting to mess with the vss
