You are soldering to the leads of the original dips that are sticking through the bottom. The pcb fits snuggly around the leads so IMHO soldering should be super easy. Maybe some of the others who have installed the other remotes can chime in.

If you add some more flux and just tap every joint with a hot iron those joints will look perfect.
Looks like you missed second pin from right, tho.
Now just waiting on the dual crystal and stereo boards, oh and a case.
Is this 5V cable necessary to connect, are there any games that requiry it? Thanks in advance.
