[BB72CHEVKT]

This is a heat only truck. I just checked and it is new wiring from the switch to the resistor. I am not sure if the painless kit had this part premade or if the shop had to wire it and got something backwards? Here are some pics of both ends. The end that goes to the switch which is melted has blue wire on top, yellow with white line in the middle, yellow bottom left and there was a black power wire on bottom right. The second pic goes to the resistor and has blue wire on top, lower left is yellow and white, lower right is yellow wire and orange wire going to blower.
