Best I can do is hit GM catalog. It's listing 25037332 as the p/n but You should look at a pic of that part number on
Amazon to confirm it's the same. It says it's compatible with 2-wire or 1-wire, but I can't confirm this is your part so don't blame me later

I can't check the forum daily. If I don't reply to you within 24 hours,
drop me a PM! I'm (hopefully) still alive and will reply faster to a PM.
