Ed has given you the absolute best info there is! you do NOT absolutely need the D ended part number. it has been discontinued by the motorcompany, so used or old NOS is all you're gonna get.68921-01, a b, c or d will work for the bike.
what else do you need to know.
find it on ebay or from a reputable salvage yard and be done with it!!!!

Searching Ebay this very second
"68921-01" 3 results an 01, an 01A and an 01C.
"68923-00" Several revisions available.
The security one should have a key fob if he goes that route. I have a couple security ones and fobs but this is not a sale thread and I think there are ample on fleabay.
I looked in a 2001 parts book for Softail as I do not have a 2002 parts book. That is how I gave you the numbers above along with what I know about how HD revised numbers back then. Also, I truly do not remember any changes from the 01 to the 02 softail. A revision letter could literally be any change, and if this were an 04 Softail it would be a big deal. You could create a post asking for someone with a 2002 parts book or you could call around and ask for the number from the book - NOT the online catalogs as they will all say D. Then you will absolutely know what the 2002 book said. Even if it were revved there is no way it would be past an A.

Not only a parts catalog for 2002 matters, but so does the "Copyright" date on page 2 of the parts catalog...
For example, I have a 2001 Softail Parts Catalog, but it says "copyright 2012". So it shows all the updates to 2012 in the catalog. It shows the "D" version...
I do have a 2003 Softail Parts Catalog, "copyright 2002". That means the 2003 copy wasn't changed from the 2002 copy. It shows:
TSM (no security) #68921-01B
TSSM (w/security) #68923-00B
Having said that, I still believe the "-01" & "01-A" versions of the TSM, and the "-00" & "-00A" versions of the TSSM will work in the 2002 bikes..

I have both a 2001 & 2003 with the TSSM modules. I have not had one go bad, but if it did, because it has security, it could keep the bike from starting. It also controls the tip sensor, so maybe that could disable a bike if the TSSM fails.
The EFI bikes with a TSSM need a complicated "Password Learning" procedure for the TSSM and the ECU to become married together and work. This can be an issue because if the TSSM fails, and the bike won't start, you need to replace the TSSM and complete the password learning to get the bike to start.
On the TSM module, it controls the turn signals and the "Tip Sensor", so not sure what happens there... I guess it could disable the bike via the tip sensor circuits if it goes bad, but I don't know.
The carb models with a TSSM, or replacing any TSM (non security) modules, are pretty much just able to switch around.
I have read rumors that there is a vendor, or two, working on an aftermarket TSM and TSSM. I can't remember if it was Custom Dynamics or one of the other vendors. That would be a great addition to those of us who want to keep our old bikes running... right now, the main repair for a TSM or TSSM is through eBay and the used TSM/TSSM market... that's always a crap shoot...

But, I was asking if you have ideas or knowledge of what actually happens to the TSSM & TSM to cause them to fail.

I am ignorant about documented causes of failure for a TSSM/TSM.
I could only guess that it could fail from the usual list of suspects that can cause any electrical component to fail; power spike, water intrusion, excessive heat, etc.
However, I have no specifics from an actual failure to draw on...

This is a pic for my 2003 Heritage. I believe your 2002 Fatboy is the same. It's mounted horizontally, above the siren if you have one, with a large, grey connector.
Note: the charcoal gas tank vent filter at the bottom is only on CA models....
PS- I just saw your PM. If you pulled a bad TSM from the bike, that big connector HAS to be there somewhere? As you can see from the pic, it comes into that area from the top cam chest side of the bike and has a secondary connector split off of it for the Security siren. I don't know how you could miss it?
