So, I've been able to retro fit a seatbelt buckle that activates the warning light light on the dashboard. The wiring to the dash may be allready fitted to your car depending on year, and optional equiptiment. The thing will be to see if you can find the connector in the 2nd picture.

 

It's a case of running 2 wires from this connector under the glovebox (the white connector with 1green wire, 1brown wire) to the new buckle and the light on the dash should illuminate when the seatbelt is uncliped.

The hardest bit will be finding a seatbelt buckel with warning connector that fits (I used one from a seat ibiza, but had to modify it to fit)

I will say that this might not be the case for all models, and that my car is a Mk2 facelift felicia with central locking, and the 1.3mpi engine.

And I have since found that it is kind of pointless also, because I allready drive everywhere with my seatbelt on, but It's a nice little function to have on the dash.

That Seat belt warning light never-ever lighted in my Felicia from the 1st day that i bought my Trusty.

I could (and I can) drive without the seat belt On.

I was also thinking about adding this function too. There is an unused seat belt warning light in my dashboard.

Do you know the OEM number for the parts you used or at least which model year for SEAT Ibiza?

Your car is a favorit is it not, which means that the ibiza belt buckle would not fit, because early felicia's and favorit's used a diffrent seatbelt latching design / style (I seem to remember)

Your best chance will probably be a generic china belt buckle with warning wire connector

Also you will have to start from the begining with the wiring connector to see if the favorit has a unused connector for the seatbelt warning light
