Question about Racing Seats & Airbag

[sixpax]

Equinox has a great DIY and there are several other threads a search provided great info on.

However, I notice that in his DIY he specifies a 4.7 ohm 1/2 watt resistor to disable airbag warning each side. Yet when links are posted to amazon and other sites to buy the resistor and they all link to a 4.7 ohm 1/4 watt resistor.

Sooo...curious as to which one is correct ? 1/2 watt or 1/4 watt ?

Also curious if there is a difference between a 4.7 ohm 1/2 watt metal resistor and a 4.7 ohm 1/2 watt carbon resistor besides the obvious difference in material used to make them ?

And lastly, I have 4 point harnesses I am putting in for each side, so will be removing the stock seat belts. Will this cause the seat belt light to stay on and the chime to ring constantly ?

Thanks in advance for any input ...
