73' 450SL Turn Signal Flasher

I would appreciate some help from someone in locating the flasher for the turn signals on my 73' 450SL. When I bought the car some of the fuses were not installed. Once I installed all the fuses some funny things started happening.

However one of the bad things was that the flasher slowly quit working. Not even the emergency flashers work. I thought at first there was a bulb out because it started a double time flash. Now they just come on solid.

Thanks in advance
