Speedo & tach not working in 95 Jetta VR6

My speedometer and tach both just stopped working. THe rest of the dash is fine, and cruise control still works (I don’t know how fast I’m going but it maintains speed). so this seems likely to be a lose connection of some sort.

So where are the likely suspects and can I get to them without taking the dash apart? (i.e. I’d take it to be serviced if that is required)
