VIDEO tutorial: Volvo 850 VDO odometer repair and board computer installation

My Friend own a Volvo 850 GLE and he wants to replace his standard info display (T° and clock only) with a most complete board computer (T°, clock, actual and average speed/consumption) normally installed on most luxurious version like GLT, T-5 and  "R".

Volvo 850 board computer

GLE versions, normally have a Yazaky cluster that not permit to install board computer; to do this the only possible way is installing a VDO cluster.
At first glance VDO and Yazaky differ for the instrument position (in Yazaky they are 3 different instrument separated from one and another, in VDO all instruments are placed in a single flat framework; nevertheless, linking connector are identical  for both, so the 2 instruments are interchangeable.

I have a VDO instrument, but without board computer, odometer is broken (classic gear issue) and km displayed are not correct, so had to dismantle and ripair it, and I had to e draw back km from 181.000 to 59.000.
Moreover I have installed board computer instead of classic display.

I made a video to exactly show you that I did...
