1991 Toyota Camry turn signal / Hazards

My Camry would intermittently loose the use of turn signals. The signal indicator lights on the dash would stop working and no noise. Now they are off for good.

The hazard button has no effect either. The button also doesn't light up.

I bought a new flasher unit but can't locate the proper place to install it. I've looked at the fuse panel on the drivers and passenger sides and the engine.

Can you give me a very specific location of where the flasher unit is located? A diagram would be great if you have one.

Any other ideas of what could be causing this problem?

Thanks.
