Actually, I would recommend leaving the THG pin in place and then connecting the MAT sensor to the two wires provided for the EGR temp sensor on California cars. On CA cars, you can unscrew the EGR temp sensor from the EGR pipe and leave it on a shelf or throw it away. On non-CA cars, the 2-pin connector still exists on the engine harness down near the distributor, but it has a jumper cap plugged into it to fool the ECU into not throwing a 71 CEL code. It may be covered and secured with electrical tape to keep it from flopping around. Just look down, find this connector, pull off the jumper cap and hook up the MAT sensor to the two wires there (one will be sensor ground and the other THG). There is no polarity on the MAT sensor, so either wire can go to either side of the sensor. This minimizes the number of wires you have to route past the firewall.
