I bought two power seats from a 1998 S70 to replace the manual seats in my 1999 S70. I did the search on this forum to figure out the differences and I see there are some fuses and maybe a relay to add to the fuse block. What I have not seen is there appears to be a difference in the wiring. The '98 S70 only had two wires coming out of the floor on the drivers side while my car has four wires. The passenger side on the '98 had one wire and my car has four (same as driver side on my car). On my car there are only two wire connections that are actually connected to the seat the other two are just connected to dummy blank connectors. It looks like one of the wires is for the air bag and the other might be for the seat belt switch. What I'm not sure about is how are the air bags connected on the new power seats? Is the wiring in my '99 already setup to handle the electric seats and the air bags?
