Beware: There are so many versions of the Corolla and this guys sequential light that things vary considerably from Corolla to Corolla. The set up I have is was easier and you do NOT have to unscrew anything. A skinny flat head screw driver can reach in there to release the blinker unit. It's all about plug and play. His unit seems a much-to-do procedure. But, good job anyway! Thanks.
Peccato aver saltato la parte più interessante: quando hai rimosso la calotta e la freccia. Era la parte più utile per chi deve fare questo lavoro. Molto attento al resto, sì..
