Inside your GWX installation you will find an exe. labelled JSGME. Right click on it and choose 'send to desktop' this will create a shortcut.
Within the same folder you will see a 'MODS' folder. This contains optional mods which can be loaded by JSGME.
You need to extract the two files that you have and copy them into the MODS folder.
Then, if you open JSGME via the shortcut on your desktop you will see a list of optional mods on the left. You can highlight these and click on the > button to move them to the right side and enable them.
You have not mentioned whether you are using SH3 Commander, if you are not then after you have enabled the optional mods you can fire up SH3 and enjoy.
If you are using SH3Cmdr then make sure it is 'Rolled Back' before enabling any mods.
I hope this is clear, if not just ask again.
