fitting parts from other vauxhalls

I think you can do SPS programming on it if you enter the donor VIN in the SPS menu.
But SPS will never let you program the Insignia cluster with Meriva options unfortunately. However, getting the EEPROM setup correctly will help.

For my test cluster I soldered 8 wires in parallel to a dip-soic adapter like this

With simple header pins it now fits into the programmers' ZIF socket perfectly.
