How do I connect shift control cables to my mercury 7.5 outboards shift lever ?

[davhen2311]

I have been given an old single lever control box with cables that has been used in the past but don't know what engine it was used with, hopefully I can hook it up to my mercury somehow. The control box has 2 teleflex cables that have plastic ends with a hole on each at the ends. Hopefully someone with some knowledge can guide me on what brackets etc I need to connect these to the outboard. It looks like one cable somehow connects to the shift lever under the hood and not sure where the other goes.

My outboard is a 1980's Mercury 7.5 Thunderbolt

This is my first time working with outboards as you can probably tell lol
