AIRBAGS - with Front Pass Seat disconnected

[JustPassinThru]

Greetings - new to the forum but a Yaris owner for four years. I'm on my second; had a 2009 and now a 2012.

The price of gas being what it is, I sold my truck and now have to make do with just the Toy. What with my needs it can be a bit of work.

Right now, I'm looking at a business/pleasure trip to Florida. There just is NOT the interior space - on another car I once owned, one without seat airbags, I took out the front passenger seat. Tremendous difference - doubles the useful room.

Now I knew unplugging the seat airbag would set off the PASSENGER light. What I did NOT know was that it would switch off the WHOLE AIRBAG system; and set the Seat Belt warning light flashing.

Does anyone know how I might find what terminals to jump, or shunt, or put resistance on, that might (1) turn off the Seat Belt light; and (2) switch on the airbag system? I mean...if nobody's in the front seat, the passenger side is switched off anyway. So...how might I dummy this system?

A trip to Florida is 1600 miles each way. That's a lot of driving; bad things can happen. AND...I might want to keep the front seat out for awhile afterward. IF I can make the system work again.
