hopefully it will come with the latest software installed.

 

..... that is hopeful news ... thanks

 

It should not need programming. Just works out of the box. When I got a new one I just plugged it right in and was good to go.

 

Even better news! - Thanks again, I'll sleep better

 

Update
New module arrived today and works 100% so all's good

Now left with two working modules without CPU's, one got fried by accident, the other has an stuck output pin (Drivers Window Up)

The modules themselves are all OK, just need a couple of programmed CPU's, should someone have a couple

On the plus side I've learnt a lot about the module and fully reversed engineered it (Covid boredom)

There is one puzzling question though regarding the Auto Day/Night mirror wiring.

The main connector C2 (26-Way) shows C2-10 as the signal and C2-12 the low reference, these lines internally connect to C3 (10-Way) C3-7 and C3-8 respectively, but don't connect with any logic.

However there are 3 unassigned outputs - C2-1, C2-24/25 and C2-26, there are also 2 unassigned inputs, C2-17 and C2-19.

As I only have a 2004 wiring diagram, could it be the wiring has changed?

If anyone has any more info on this bit, It would be good to have the full story .. cheers!.
