Street and Performance sells the exact adaptor you need. Metric to 3/8 pipe thread. Only thing that sucks is that they're polished. Yuck! Lol

i have the sensor already i just had to order a replacement pigtail from ebay. should be here today. gotta figure out what pins it connects to the pcm.

its a three wire sensor two for the computer and one for the gauge i have one in my truck just remove old and install

you can get it from a junk yard off the overflow or any of the three wire with the purple seal

the ones side by side go to pcm other one goes to gauge

well i have the single wire one from the old engine which im going to put on rear of the passenger side head then the 5.3 sensor will go in the front of the driver side head. the 5.3 is a 2wire plug.

Check out this temp sensor setup http://www.ebay.com/itm/LS1-LS2-LS6-...09477265333595 I think i am going to change to this because the location of the adapter and old temp sensor in the back of the passenger side head is the way of my spark plug wire and very close to the shoenfeld headers.Also makes changing that back spark plug a real pain.

that's what i'm using & it works great.
