Engine Temp

Yes you have to use a separate temperature sender for your gauge you are running , I was going to use the plug in the front housing .

The operation of the gauges from the factory on the new stuff uses info sent from the temperature sensor to the pcm and into a Controller Area Network (CAN) data bus to transfer the information to the gauges, so there is no need for a separate temperature sender.

Street and performance has a good link for info how to install, scan to the bottom:
