Yes, there should be a connector under the carpet, because when i switched int., all I had to do was plug and play with every thing but the mirrors. For those you need to install the harness, which is not hard, and plug it in to the fuse-box. On my old style (pre96) XJ's, it plugs in to the lower part of the box, and only used a single wire to plug in. The seats already had wires run in the body, but I did have to run power to the harness from the box. Needs 30 amp power, mine uses a breaker. Hope that this helps.
