I remember seeing a post a while back that had a three wire coolant temp sensor. 2 wires were for the PCM and the other was for the guage. I can't find that post. Does anyone know a part number or have experience with this. The post said something about a dealership installing one as an upgrade. I want to do this to move the guage wire away from my headers.

 

My buddy did this to his Impala. If you don't have any luck here, you could try one of their boards.

 

Could you give me the web address and his screen name. I wish I could find the thread on here. I think this will also make it easier to get at my first two plugs.

 

Found it. It is a pretty good write up as well. http://www.theherd.com/articles/lt4_temp.html The Borg Warner part number is WT3024.
