I found all the info in the search area of the FAQ.

Three part numbers that will work in the 240.
#13913 Bosh
#13942 Bosh
#13953 Bosh

All are WAY cheaper than buying the one listed for the 240 Volvo.

Cut the leads to the old one and use PosiLock connections to splice in your old wire harness to the new one. I went with 13942 but have heard many go with the 13913. It was just what was available from my auto store at the time.

BTW, it's way easier to do this if you take yours out first and disconnect the wire harness. Then cut and splice at the bench. Also I just bought a O2 offset socket wrench at Harbor Freight Tools for $4.99..I had to use a cheater bar on my ratchet for extra leverage but it does come out.
