where do you place the "Water Temp" sensor. any pics would help. thx
Each of the heads will have a port in it for the water temp sensor. On the driver's side of the vehicle, it will be at the front of the engine and on the passenger side, it will end up at the back. The port looks like this:

You'll put the sensor in one head and can plug the other one if you like. What I did, was use an FD sensor in one port for my gauges and the GM sensor in the other head for the PCM.
