Hi

i am currently fitting a 94 jap wrx halfcut into my subaru vortex and have a question about the second sensor on the dump pipe after the cat is this a o2 sensor or cat overtemp? as there is another sensor before the turbo on the manifold??


also the throttle pedal has a micro switch on it is this required for the conversion, my books are telling me nuffing is it just a import thing?

any info would be much appreciated thanks
