Well, yes and no. You'll need the sensor and mount it in front of the radiator. With the 99-02 trucks they have a transmission cooler up front (typically the ones with the towing option) that is where the sensor is secured. You'll have to find a place to mount it. Connect the pigtail and then run 18 gauge wire (I wrap mine in 1/4" conduit) back through the firewall, up and over to the mirror.

Does it have a 7 pin connector on the back of the mirror? You'll need the connector and wiring (mirror pigtail) to wire everything in. I bought one off of eBay that came with the pigtail (had all 7 wires) - my truck already had the wiring harness tucked up in the headliner but it only had 3 wires instead of the 5 I needed. I took out a couple of leads from the old pigtail and put them in the one that was in the truck and connected my temp sensor that way.
