As I said earlier, I got the etacs (fuse box) from the totaled lancer and all we did was take the old one out put the new one in car works great all functions work as they should, the only thing that shows is a system error but after you start driving, press info button on the dashboard the system error will dissappear and you can switch between the other options that originally are there. I didn't want to pay so much money to get the whole part from the dealer because it is so expensive. And the system error that shows up doesn't bother me at qll.
