Coolant temperature sensor connector 2000 to 2002

Hey guys,
I'm trying to find out if the coolant temperature sensor changed from year 2000 to 2002?
I bought a 2002 harness for my 2000 Boxster S V8 swap and I can't get the water temperature gauge to work. From the diagrams, it seems like the wiring was switched from 4 to 2 wire connector? Is this correct? Did the sensor change as well? Can I still make it work somehow with two wires?

Thanks!

Does anyone know where I can get a connector pigtail?

Yes to all your questions.

No I don't know how to make it work other than installing a Porsche approved engine.

Haha the Porsche approved engine is not longer an option! Thanks for the input, I guess I just have to get a connector pigtail somewhere.

The right sensor should only be about $20-$25.

Hey John,
I think the issue is in the harness not the sensor (but im not sure tbh). The previous owner sold the harness and butchered some of the body wiring. Now I'm trying to piece it all together. Yours is a 2000 Boxster right? Mind checking what sensor you have and how many wires go to it? This is the sensor that I'm using, which has 2 pins, so I don't get how it can have 4 wires.

Vlad, I just came across the same problem installing a 2001 3.4 into my 2000 3.2 S.
The 3.4 and a 1999 2.5 both have the 4 prong coolant temp sensor but every 3.2 harness I looked at has the two prong sensor. Not sure what the extra wires are for

I think some 2000 3.2s got the 4 pin and some 2 pin sensors. The two extra wires are for the instrument cluster to display temperature
