Hello everyone. I just bought a set of 18 Denali seats for my 98 k1500. I really would love to use the heated and cooled function. I don't care to use any of the original switches or lin bus. So my question is this. Can I run 12 volt to the fan leads itself with a switch and perhaps a controller in the circuit? If not, how about replacing just the fan that runs 12 volt instead of lin bus? Same question for the heating element. Can I run 12 volt to it with a thermistor? AliExpress sells the fan kit, switches.and controller for cheap but I have my doubts. I have read all the threads here but most are just people looking to stock with all factory switches and plugs. I just want to make what I have work without taking off the leather which is flawless. Any help is appreciated. God bless.
