I want to contact them so they can look up what ECU is the correct one for my 88 300TE and make sure there are no updated modules (I need to make sure I have the correct one in my car)...

I can't find anything that specifies part search apart from classic cars which it states must be 25years or older.

Anybody know where I could email them looking for this information?
