I just got through fixing my factory A/C. You'll have the underdash unit (evaporator)to screw to the bottom of the dash (there should be a bracket that bolts to the firewall to hold the back of it up). Wires should plug into the fuse box (holes marked with A/C and A/C compressor). two hoses run from the underdash unit; the big one goes to the compressor, the smaller one goes to the drier(little cylinder), then you have the condensor (looks like a small radiator and goes in front of the regular radiator). There will be a hose running from the condensor to the other fitting on the compressor, and then the smaller output on the condensor goes to the other side of the drier. All basically bolt on stuff, you just have to have the time to do it. I'm assuming this came with the brackets to mount the compressor and remount the alternator. You probably will be best off taking it to a shop where the will vacuum the system down and then it just need to be charged. Mount everything yourself and take it to the pros to charge it. Good luck.
