I did a swap on a 92 Civic Si. From what I was told, since my car came with vtec, the fuse box under the dash was equipped to plug-and play with a power window set-up. I'm not sure what a dx/lx fuse box has or doesn't have. You'll need the behind-the-dash wiring that goes from the passenger side door and connects with the driver side harness, which then goes to the fuse box. You'll also need a relay and proper gauge fuses.
