Just adding that this old thread saved me a lot of hassle, too.
After looking (upside down) for 20 minutes I searched here.
Even after I read this thread I had to poke around...re-read thread...and poke around again before I found the flasher unit.
I'll add a few things...first, it is further up toward the front of the dash than I was expecting.
Second, mine had a piece of black foam around it making it that much more difficult to see.
Third, the replacement unit did not have a spot for the clasp that the original part was fixed to the dash with.
So instead of pushing it back where it was, and where it would rattle a bit on the dash since it isn't fixed in place.
I let it rest on top of some other wiring. Hope that doesn't hurt anything.
Once you do find it, it is plug and play.
