We relocated the factory seat belt buckles and respective wiring to the sparco seats and reconnected the wire harnesses, with the exception of the air bag modules (obviously). We expected to see the amber 'airbag off' light to the right of the AC vent, as well as the red airbag light on the dash cluster itself. What we didn't expect to see is a red flashing passenger seat belt light on the same panel to the right of the AC vent where the airbag on/off lights are.

The passenger seat belt buckle had two wire harnesses for what we believed to be the seat belt and airbag. The driver seat had a third harness (no idea what for). Both seat belts buckle and there is no beeping. Unbuckling the driver seat belt produces a red seat belt light on the dash cluster, as normal. Buckling the driver seat belt makes that light go away, so I'm sure the flashing seat belt light on the right side in the air bag on/off light area is related to the passenger seat belt. Buckling the passenger seat belt doesn't make the light disappear. We tested coming to a hard stop and both seat belts still lock-up under hard braking. Everything appears to be normal, so I can't understand why the blinking passenger seat belt light appeared. The only thing we didn't reconnect on the passenger seat was the airbag wire harness.

I'm searching the forum/internet for answers but if anyone knows what we did wrong, I would greatly appreciate the guidance.

Those seats look great in the yaris. Probably a bit more comfortable than stock, I'm guessing

I think the passenger light has something to do with the sensor in the oem seat that detects the weight of when someone is sitting there and maybe the lack of that sensor is causing the light...
