Ok I have a 96 Hatchback CX, and we know that this is a really cheap car! I was to add power wondows and power door locks with an OEM look (use OEM switches). How can I do it? Any suggetsions? Can I get the door pannels off another car? And I also want to add a tachometer. Should I just buy an afetrmarket tach? or is it possible to add the EX guage cluster? Is it plug and play?
