Btw….here’s how to deal with getting Flat Ribbon Cable through round holes……..once split into groups (not all the way to the ends) and heat shrink, then temporarily roll/curl the ends to pass through the round holes, then re flatten the ends.
When heat shrinking …never stay long in 1 spot, move along the length evenly with the heat gun…. otherwise the heat may melt the insulation of the Flat Ribbon if it is to HOT which might cause shorts or intermittent problems……However this method is used in industry with experience.
