Ok, I'll pony up the cash and give this a shot. If this doesn't work, it's OLMAF for sure.

I found out today that you can't find anything with dealers with that part #, as it's the internal Bosch number. Did some intensive googling tonight and found the store number.
Any tips on mating the wires as I'll be splicing it with a connector from an extension? I'm also going to try one side first before I invest in both.

Yep, on one of the Bosch pdf's they had installation instructions and the kit appears very well thought out. Hopefully I'll find one locally today and get installed by the weekend.
Thanks to you guys for the help so far and I'll update after the install.

Installation instructions are on page 28.
Ok, after searching on the internet, I found info that indicated Bosch part # 0-258-986-505 corresponded to a shelf part # of 15738. This is the one I ordered. The instructions that came with it showed it to have two heater wires, one signal wire and a ground. Yet as pictured above in the post by Mr. Prick, the GM four prong connector has two signal connections, one heater, and one ground. Is 15738 the right sensor? If so, how do you wire it?
I found a local Bosch expert who searched his current parts books and could not find any reference to that original part number. He said it may have been superceded but there is not reference to that original number.
Further help anyone?

As with ANY Bosch 4 wire sensor. The two white wires are the heater power and ground....either white will work.
The black is sensor voltage 0-1 volt and the gray is sensor ground.

Thanks. I've gotten more info from PM's corroborating what you say. It should wire up ok, and it tested to 2.6 ohms meaning that it is the hotter 18w type.
I've been out of town, but I should get it wired up some time this week and report back.
