I've had those resistors blow out while testing because I had it hanging just as you did and it wasn't getting airflow. Took about 30 seconds to burn out . Thanks for the video
This is a voltage variable control wire. I have seen this in Miatas I believe. The internal contacts drive the motor based on the voltage changes. I see a resistor here and careful with those resistors not having airflow, they do burn out if not left installed since the air from the fan keeps it cool.
Thank you for great content again! I have one question. Would you share with me what is the software called that you showed us wiring diagram on this video first part please?
