Yeah, right after the plug. Exactly as on the picture. One wire of the Resistor on the yellow, the other wire of the resistor on the black. That is if. If your hyper flashing still persists, you will need a adjustable signal light relay for Toyota, this delay is located under the steering wheel. If VSC doesn't disappear in 7 days then the next options are the PCV valve and vacuum lines. Then wait another week and if it doesn't disappear, then scan the car with a OBD2. Then possibly changed O2 sensors and MF sensor. Lastly will be the ABS sensors. But if you wanna void all the hassle and have the $$$, then take to a mechanic and ask for warranty, and if problem is not fixed, then they can install the next parts free of charge (charging only for the parts). You can find my project on I G IS250_Sage
My warning light is back, so I will do the vacuum lines and O2 sensors next. Then scan the car.
