did i swap the right temp sensor?

[1991 e30 bmw 318is]

but i don't think i can do this because, the original sensor needs to be hooked up for the dme?

I think I know what I'm doing now...

2 prong it was a direct fit. the e36 harness plugged right in it......but it does nothing...

From what ive read, there is tapping/dieing involved in the temp sensor install for m20 guys.
Now, since my car is an m3, i was told that the temp sensor would work, and mine also screwed right into the head.
Does yours have 1 prong, or 2?
