Temp sending unit
Hi, we are putting a 350 in a 1984 blazer (orig. 2.8L) and the temp sensor on the 2.8 used a 2 prong connection. The 350 sensor uses a 1 prong sending unit. We wish to retain stock guages if possible. Is there any way to make the two prong guage and one prong unit work together?

Thanks for the help!:welcome:

Take the sensor out of the 2.8 and put it in the 350....................

where would I find one of those??

UAP, CTC........any auto parts place. Take both senders in and say you want to put this sender in this size hole. They will fix you up.

Doc here:pimp:

If you use an adapter (which is perfectly fine) Assuming the new sender is SMALLER in diameter than the one you have now...

Be Sure that when the sender "bottoms out" in the adapter that the bourdon Tube Extends PAST the adapter into the water stream in the block. Otherwise it may be grossly in error , as much as 30 to 50 degrees...(moving water is hotter than static water..)

Another way to go is, use the stock sender If it's resistance compatible with the gauge,(around 70 to 100 ohms I think) and just abandon one of the wires at the gauge...You COULD use the other tap for an electric fan if you have one, or plan a future one, The data will be the same off either pin.

Hope it helps!
