Surprisingly you still have a cable problem!
 
I’m suspecting you creased the cable sharply at the corners, this is a common issue as in doing so you damage it! What you need is a smooth arc with not sharp bends. I use a Bic pen ink tube or bamboo cooking skewer to help me form the curve in the ribbon cable at the bend points. In addition, the aluminum uppercase is a bit rough and over time abrade the cable. To help prevent this I place a strip of electricians tape on the upper case where the cable crosses over. You’ll also need to get a new cable: [product|IF163-026https://www.ifixit.com/Store/Mac/MacBook-Pro-13-Inch-Unibody-Mid-2012-Hard-Drive-Cable/IF163-041?o=2]

The other thing here is to disconnect the battery and press the power button keeping it pressed for a good minute. This will discharge the logic so any error conditions will be flushed. Using a known good external boot drive (see below) you should be able to get the system to boot. Then run Disk Utility on your new SSD to format it with a GUID partition and then install your OS.
 
Very Important! High Sierra and Mojave will alter the file system from the older HFS+ to APFS! I do strongly recommend sticking with Sierra so you don’t get into the High Sierra issues (Mojave is not supposed by Apple on your system). Systems with SATA based drives do better with HFS+ (Sierra).
