Check out the "InitStartUp" function. It has some things, yeah... a lot of things. Looking at https://forum.wc3edit.net/tutorials-cheatpacks-f80/jjcp-1-24b-e-t13526.html cheat sheet in this thread, it feel like it is JJCP indeed. Activation code is in "InitControl". A little bit obscure, but I explained it earlier.
Fun fact that your previous colleague bumped version from 1.2c to 1.3 so everybody thinks v1.3 is a new one. Same thing with v1.4. I saw no v1.3/v1.4 without JJCP. So you don't even need to distribute your version, just join any lobby and you're free to go.
So you want somebody to add your activation code to v1.4? Better give a try to a current one. For some maps, activation code is "SynovialTree#XXXXelvoe", and for others it is just "SynovialTree#XXXX". You just need to figure out what is XXXX.
