Chosen Solution

So I found a 2015 i7 16gb ram 1.5 gb vram, 512gb ssd for 660 but there is a major issue, the connector for the keyboard is torn off

would it be possible to just get some solder infused in flux and put it on and solder the connector directly without replacing it. Thanks I realize that this isn’t the right way to fix it, I’m just wondering if it would be a usable option since I can’t find a place to buy the connector Update (06/23/2020) So replacing the trackpad will also make the keyboard work again? asking because the keyboard and trackpad don’t work

The connector that is missing is part of the trackpad

I would just replace it as I’m sure you really can’t solder the ribbon down without creating a short or causing other issues. MacBook Pro 13" Retina (Early 2015) Trackpad and here’s the guide MacBook Pro 13" Retina Display Early 2015 Trackpad Replacement
