Bx 4070a Cab Dashboard and heater Wiring diagrams

Unfortunately, there are no diagrams that I can find. The heater has its own manual. The BX-80 series cab heater is p/n BX4071. The power supply comes into the heater on the right side of the cab to the heater breaker then to the switch which feeds both heater fans. If you look at my other post on the heater you will see how to access the heater cores, fans, and power controls. Part numbers are listed in the manual but no service drawings or instructions. If you need access to the upper light controls I recommend removing the roof as that is what I ended up doing to install a stobe light. The cab manual details power sourcing for the cab which includes heater wiring. I have included a link to the cab manual so you can find the power source. I did not find a manual on line for the heater so I scanned the install page that shows where the wiring comes into the heater. I have called my dealer and Curtis on the heater thing and neither could answer my question. The cab and the heater are built for Kubota by Curtis and do leave you guessing on some of it.

Each thing you add to the cab has its own part number and manual. The front LED lights are BX4074. The rear LED lights are BX4075. The front wiper is BX4072.

I have the instructions for mounting the cab in a PDF. The file is too large to post to the forums.

Just in case it helps, my BX Curtis cab has the following: I doubt Curtis reinvents the wheel for each cab/heater, so it might be consistent:
