I did door locks on a 1st gen, it's cheaper to go aftermarket rather than oem. And if the 2nd gens are like the 1st gens, you don't have the wiring in the doors for the windows or door locks.
If you are going oem, you'll need, window regs, door card with switches, wiring harness, door actuators. If you want remote door locks you'll also need whatever goes along with that.
Aftermarket, buy a kit from SPAL for the windows, buy a door lock kit on ebay. REMOTE POWER DOOR LOCK Kit on eBay
I bought that kit and it's worked well so far.
