I have an old Webasto DW80. It only achieves around 60-65c which isn’t enough to be affective for a matrix blown heater. See the chart below.

Someone online suggested the heater will work in the same way as a Thermo 90 which is the model that replace it and that I could simply put a wire from the negative to pin B6 and it would step up the temperature.see below from the Thermo 90 manual.

Before I go messing I wanted to ask if anyone with experience with Webasto installation would know if this was correct?
