Default Low Coolant Sensor Location?

I just went to pick up my 1994 SSEi from the shop where the radiator and A/C condensor were replaced. Noticed right away that there was a wire/plug dangling free near the radiator and the shop had bent a paperclip in the plug. Now i get the "low coolant" message everytime i drive my car. I asked the shop and the guy said the old radiator had a sensor, the new one doesn't. My old radiator was still at the shop though and i looked all over it and didn't see a socket anywhere on it, unless it hangs off to the side and it had broken off when they removed it.

So i was wondering if in fact the GM radiator had the sensor built in, or if the sensor is somewhere else? Should i ask the shop to get me a different radiator (it would be a bit of a pain), or is there a good fix to prevent getting the coolant message all the time? Thanks everyone.

The sensor is located on the passenger side of the radiator between the two transmission holes.

Sounds like the shop installed the wrong radiator if it doesn't have the hole for the sensor. Check radiatorbarn and you'll note the prices are not much different.

If you remove the paperclip, I believe the default is no light.
