I would much prefer this to having to hack and slash my wiring to add load resistors that may not even work properly...
Does anyone know if the 300 uses any of the models listed here?
LED Flashers Blinkers Resistors Load Equalizers for Turn Signal Replacement Bulbs Rapid Flashing Fix(the little black boxes, first listing under the navigation)
I tried finding the part number on the net for the 300, but no luck

While I have done nothing with LED lighting in my "C", after review of the wiring diagrams, I'd have to say that there probably is no "blinker module" as such used as the turn indicator and hazard warning lamps are controlled by the Front Control Module (a.k.a. FCM, that 5" x 7" shiny metal box mounted to the front of the Integrated Power Module (IPM) ), which is probably why Autoluminations does not list anything. I'd say that we are pretty much stuck with connecting some kind of additional load to compensate for the reduced current draw of the LED's.
Again, I've done nothing myself, but if I were to do something I would probably install all of the load resistors as a cluster directly to the wires where they exit the IPM, and run a single ground wire. All is easily accessible by raising the IPM.
Further, here's an excerpt from the service manual explaining the FCM's function. Interestingly, it mentions that it controls "the click rate of an electromechanical relay soldered onto the EMIC electronic circuit board that emulates the sound emitted by a conventional turn signal flasher."

So, despite what you think you hear, there is no flasher unit at all!
