Ford Mustang 2006 Problem

Good I need help to solve a problem with my Mustang's flashing.
The problem itself that when they did the adaptation for Spain did not do it well and the flashing work faster than normal as if a bulb was missing.
I was looking and the truth is that I do not clarify with the vehicle wiring, I have tried to put a resistnice equivalent to a bulb and it does not improve if someone has made the modification well that explains how to correct it thanks.

You could try by changing the ampoules to say if they are of large balloon put it small and if they are small, if they are mixed it usually happens.
