Yes. No wires to be seen on my van's seats.
Five bolts, 3xT40, 2xT55 (towards rear). 2 bolts nearside, 3 middle. These seem to have had thread locking compound applied. They go through plastic spacers (different diameter insides) under the seat retaining flanges. Middle middle bolt (T40) needed working to and fro as I was worried that the Torx bit would shear (bolts go through to underside and collect grot) but a straightforward job.
