I don't know how to do it like the tut there, but one thing you can do is open the .git file of any module with k-gff editor, and look under the tree named placeables to see how it's set up, in the .git (again, open with K-gff) of the module you're working on right click on placeables, there should be an option to add a "struct" just name it the same as it is in the other placeables from the other .git, then right click and add more entries to that struct, the type of entries you want should be labeled in parentheses in the original .git you looked at first, give them the same names as the first example (tag, resref, etc.) then fill the area after the parentheses with the type of info the example uses (you will want to use different coordinates, filenames, etc. but they should be similar to the original .git), save the .git and put it with the rest of your module files and use KT's erf builder to make a .mod file, copy that file (probably in you KT root directory) into the modules file in your kotor directory, start the game and warp to the filename of your module to see if it's there.
Sorry if that's not precise enough, I've only done it once, but that should get you going in the right direction
I'll take a quick look and check back.
edit: Just checked, your struct name should be "9" (if you look at the placeables in the original .git you should see this)
[STRUCT ID:9] that's what you want to see,
then you right click on that entry and add
make the first part of each match the original, for example the first line (float) has a first name of Bearing, you should see that in your original placeable entry.
on the other side is a number, you want that number to be different because that's direction it's pointing.
the resref is the item you want placed, you can find the name in .bif->templates->placeables, look at your original example, you should be able to find the name after resref in the placeable list.
[dword] and [byte] just have to match the ones in the original (if you look at all the placeables in the original .git these entries are all the same).
the last three are it's location in X,Y,Z coordinates, use D3 and TK's whereami armband tool ingame to get those coordinates.
I know I'm not skilled at this, but I hope that helps you some
(could somebody else help him now, it's too late for me to be going back and forth to my PC
