I found that gentle tapping with a soft mallet was easier than pliers. Very light tapping to get it started, then lots of rapid tapping to move it in the rest of the way.
To add a little more detail on the motor orientation:
The Fusion 360 CAD assembly shows that both motor plugs should face the rear of the 3D printer. So, for each of these two motor mounts the plug will be oriented differently. In other words, don’t build both of them identically to each other.
In Step 4 here you’re building up the front right motor mount. If you’re looking at the first image, the orange and red arrows are pointing at the side where the plug should be. This can also be seen in Step 8 as mentioned in the previous comments.
Then in Step 9 when you build up the front left motor mount, the connector should face a different side. Once again looking at the first image here in Step 4, it will be the side that the green arrow is facing.

3x35mm means 3mm diameter x 35 mm length dowel pins. The quantity of 4 was stated in the prior step.
