I will first do more extended test riding with the VSS disconnected to ensure that all normally work without speed input.

Yes that bombtail Laurens thumbs

Hopefully following testing with speed signal disconnected from ECU and OE TSM you will have a driveable car, with all lights working and no fuses blowing. I believe this will just leave the fuel pump back feed problem with hazards selected.

I think you can assume the issues with alternate TSM's are simply down to incompatibility and not worth worrying about.
