OEM Accessory Switch Question

OK...

To use the MB switch, connect both its pins 3 and 8 to the +12 feed ((A) in my previous drawing)
Connect pin 10 to ground (D)
Pin 7 connects to (B) (high)
Pin 4 connects to (C) (low)

I think that will do it.

Don't forget to put a suitable fuse (capable of carrying the "high" heat current) in your 12v feed.

What about pin 5

 

[ECU]

Pin 5 is the off position of the low heat.
So it should not be connected in your wiring.
