Airbag fault light on seat switch

[latch5]

Sorry guys - Posted this at the bottom of an old string ystdy by mistake.

I've done my research and thought I had all the bases covered but I still am getting a flashing air bag light when I switch from stock (driver side) to racing seat. Have changed the seats out several times trying to find the solution but I'm stumped. I know I can just live with it but would rather not.

Please double check my proceedure to and see if you have any ideas.

When I switch seats I depower the air bag system (remove fuse & neg battery cable)
- I use a full wiring harness with the race seat including the seat position sensor & yellow airbag terminator cap from Ford
- So I have the main harness hooked up
- Seat belt reciever hooked to the harneess
- the seat sensor is hooked to the harness and the magnet is in contact with the seat mount.

I repower per Ford's proceedure (ignition on - put fuse in - hook up battery)

When my stock seat is in I have no codes - When the race seat is in I have the flashing yellow bag light.

Any ideas?

PS I disarmed the seat belt warning light successfully (both seats)
