The ones I used a 1 watt and are more than enough to handle the typical voltage that the SRS system puts through it when it is in "observe" mode. It does not matter what wattage your resistor is. Below are the bags of resistors i purchased form a local electronics hobby shop 5 mins from my house, called Nutech Electronics Many cars only require 1, but the Yaris has 2 separate connectors at the airbag. I purchased 2.7 and 3 Ohm resistors and ended up using the 2.7's and they work fine. For most if not all Toyota's you use a 2-3 Ohm resistor which tricks the ecu into thinking the airbag is still present. Tom has a great video on how to install an aftermarket hub - watch it HERE I am not going to explain how to connect the hub, quick release and wheel to the car, it is fairly self explanatory by looking at it. This allows you to have a fully functioning airbag system - except for the driver one you removed. I'm going to focus this DIY on the horn wiring and the SRS airbag light bypass.
