I couldn't seem to find this, but if you swap 05-07 door cards to a 02-04, do you have to change the entire harness in the door? I have done a few in the past, but don't really want to have to buy and swap all four, especially when they are in the car. So is it possibly to just swap the switches? Like just get a pigtail and cut off the old one and connect the new one? Thanks.
