I took the interior out and can't find it. I smell where it's coming from. Passenger wheel well cavity. Maybe it fell down inside the rocker panel. It's mice. I've seen them with me own 2 eyes I did!

 

i had to take my bonneville to the shop twice to fix a wire problem because of stupid red squirls. they were chewing wires right by the passanger side front brake caliper... i was pissed when my dash lit up like a chrismas tree for the second time, so i invested in a semi auto co2 powered pellet gun, a lawn chair and a 24 pack. never had a problem since.

 

I put a box of baking soda in the stink zone. Hopefully it will suck up some of the stink.
