most likely the dye in the leather backing on the harness. You need to make it a point to lay the harness somewhere other than on the seat when you get the leather wet when washing the vehicle and let it dry before putting it back on the seat. Mine did it a little bit but it was on the black part of the seat…..

Try a little WD-40, thinner or silicone spray and see what happens. Even if it peels the yellow, you are no worse than two big brown stains
Like that!
