Product review (4 stars): How to install the shield
First, my original part number was actually W10049390, but if you go directly to Whirlpool, they say the replacement is now W10217134. If you go to various online shops, they will tell you the replacement is W10536347. However, what I actually got was W10238317. It did fit mostly, but I'll get to that.

The hoses and screws were all perfect fits, although the screws on it had washers, I didn't transfer the washers to the new screws. The cover for the wire was a bear to open, but there are two little tabs, one on each side, you have to gently pry up to get it to open.

Now, the shield, for which there are no instructions...
If you look at the images I posted, this will make a lot more sense, but here's the description.
1) There are 3 plastic pins that skip into holes to hold the wires between the pump and middle of the tub.
2) One of the holes for the shield goes in the lowest of those pins, the one closest to the rotor.
3) Another hold in the shield is for the screw closest to the drain hose.
4) The hole with the partial flap in the middle of it is for another screw to go through, the one straight back from the where the hose goes from the drain pump to the tub.

I found that this pump wasn't a perfect fit because the middle of the 3 pins to hold the wires down would not go in once the pump was in place. There just wasn't enough room. It did seem to work however, despite the number difference and fit issue.

As one last thing, I also added some 1/4" hardware cloth under the filter to keep any more coins from getting in the pump.
