    I'm swapping a GSR into my EG (VX). I'm planning to convert my VX harness for the GSR and I've noticed the GSR have two 02 sensors - one in manifold and one in cat. Can someone clarify if I need both 02 sensors or will I get away with one to pass smog. Pix would be nice on where to hook up the 02 sensor and how did you plug up the other 02 opening?

    The gsr you have is an obd2 swap. That explains the secondary o2. If you run an obd1 p72 ecu, and have a cat, passing smog should be easy. Go to a hardware store and find a bolt with that fine pitch thread to plug the bung.
