Knock Sensor Purchase? 2-Prong or 1?

Hi there,
My CEL came on recently, took into the dealer who said that no code was thrown back. But then charged me $1,500 for other repairs that were needed. Fine. Paid all that, then the light came back on. Turns out it was the knock sensor all along. Rather than fork out another $300 or so, I thought I'd replace it myself. Looks pretty standard. However, for the life of me, I can't figure out whether I need to buy a 1- or 2-prong replacement part. I'm confused as to why there is an option...so I thought I'd refer to the forum, since you're always so helpful
I have a '97 Subaru Legacy L.
Thanks in advance!

If it is the 2.5L, I'm fairly certain it is a single prong.
I have some photos of the rebuild I did on my '96 2.5L, and that one is single. Getting to it is a bit of a pain, but other than that, it should be a simple replacement!
If you're buying locally, get them both, pull the old one out, replace it with the correct one, then take the other back. ?
