VR changed auto to manual transmission

[uelik]

I am a new member and try to get same help. We changed on my sons VR wagon the auto transmission to his manual gearbox out of his old VP. Mechanically this worked perfect no problem. The only open issue is the Electronic Speedo connection. The auto hat two connections to the box one two pin plug and one big round plug with may wires. The manual has also two plugs one for the reverse lights (2 pin) and a round 3 pin for the electronic pick up for the Speedo. Any body out there knows how to rewire this connections? Any help greatly appreciated.
