If you use just the seats, you will unbolt the seats from your frames, keeping your existing wiring and tracks. If you unbolt the frames from the floorboard, then you will have to rewire everything.... Go take a look at it, if you slide the seat all the way forward, there should be a two 10mm head bolts in the front that holds the top section down to the sliders. I'm talking about the metal the seat fabric hooks to...... Then the seat has to go all the way back to access the rear bolts, and the whole seat, backrest and all, comes off the sliding tracks. They should bolt up, but I have seen some Mexico built stuff that was stamped a bit off, and the holes had to be opened up a bit, nothing serious, just required drilling the hole off center a little, or opening it up a 1/16th or so....
