I'm doing the engine prep for installation. Last little hurdle to overcome: The Coyote instructions (starting on page 26) tell me to remove the plug that accepts the 14mm key. Done. It's a big plug. Then, I am to replace that with the adapter that the water temp sender screws into. Oops. The adapter plug I found in the coyote fitment box is much smaller than the Coyote plug. One of three possibilities: a) I pulled out the wrong plug, b) I pulled the wrong adapter from the box, or c) the plug is bigger than it was when the put my kit together. Take a look.



The big hole is where I pulled the plug from. The 14mm key fit it quite nicely.

Here's the top view of the plug and the adapter I have:


Here's the bottom view:


The adapter is quite a bit smaller than the original plug.

Comments? Ideas? I'm hoping that if I can't find an adapter that fits today, I'll be able to access that hole from under the car, because the engine is going in tomorrow (Sunday).
