2019 Kia Soul, Rear Defrost Wiring

Found it! 2017-2019 2nd gen defrost trigger wire (not sure if 2nd gen 2014-2016 are the same) is in the smart junction box (fuse box lower left of steering wheel) I/P-E connector, pin 16, White wire When testing voltage it WILL read 12+ volts with car running and defrost OFF because the multimeter is reading the positive wire that is connected to one side of the relay coil waiting to be triggered with a ground signal. With defrost ON it will register a very tiny amount, around 0.22 volts Excuse my dirty car, it needs a good detail (we use it as our second/emergency car) Also I temporarily took the locking clip off the blue I/P-E connector for easier testing Running pin 16 to ground: Running pin 16 to ground SUCCESS (heating element did indeed warm up during the testing time): Measuring pin 16 voltage with car on, defrost off (normal reading as you are reading the positive wire on relay coil waiting for ground): Measuring pin 16 with car on, defrost on: THANK YOU! lee.lopez for providing me with that diagram. Made all the difference and saved me from testing MANY wires lord knows how many times each.2017 soul, 2021 soul
