Looking to replace the heater fan in my truck. There is a fairly extensive wright up on another board but no one talks about the small silver box thats attached to it. See attached picture. It appears that people are using a Delco PM136 and modify it slightly by making it wire grounded in lieu of chassis ground.
Does anyone know if the silver box is needed or not? Has anyone done this and can share some info?
Thx,
