Yes - VygisToolbox and Vpower use same cables like Unibox.
No - You cannot use Blazer cables
You have all necessary pinouts on the support areas, so you can, if you want to try, just use the connectors from the Blazer cables and build your cables for the Vpower (VygisToolbox)
Or, if it is easyer for you - you can buy Unibox cables from
www.tele-way.com by example.
