Guys, today I thought of the cable hose that went to the back door and looked at it, and I thought there are 4 cables, I think it is the rear speaker wiring, because there is only a central lock, as I know, 2 cables are going, and when you attach 2 of those cables, what is your interpretation as if I have eye color? By the way, I think the 2001 model has isofix.
