Does anyone know if the MacBook Pro 13 Late 2013 (A1493) Top Case is compatible for the MacBook Pro 13 Mid 2014 (A1502) hardware. I have come across sites that say they are compatible. However, I see the trackpad trimming for the A1493 is different from the A1502. Also, they are using different cables to attach the trackpad to the Logic Board. I am unsure if the cable will become damaged from the weird trim from the A1493 Top Case. Update (10/04/2017) The A1502 uses a different type of connector for the trackpad from what I am seeing. As opposed to the A1493, it is using a slot for the connection. From what i researched, they were considered the same top case. 13" MacBook Pro Early 2015 (A1502)

Cliff - I see where you took a left turn! You have a 2015 model not a 2014! So in this case you are correct the upper cases are different and require a different trackpad & cable. The 2015 has the cable going over the top of the battery Vs going under it (from the bottom cover viewpoint). They are different parts! 2013/14 Vs 2015 MacBook Pro 13" Retina (Late 2013/Mid 2014) Upper Case AssemblyMacBook Pro 13" Retina (Early 2015) Upper Case Assembly
Late 2013-2014 palmrest (uppercase) are compatible with each other, no difference. A1493 is the battery model number, as long as you have an A1502 2014 (not 2015), and are trying to fit an A1502 2013 palmrest assembly, it will work fine.
