MK2 VW Jetta cluster removal, diagnostics and re-fitment.

In this video we removed the cluster from a 1600 (CLX) VW Jetta, use a DC5V battery to test the fuel and temperature gauge for interest's sake, then we reassemble and reinstall the cluster to see if the speedometer is working as it should.
The speedometer cable became dislodged from the cluster, which is why the speedometer was not functioning correctly, after reassembling and reinstalling the cluster, we reconnected the speedometer cable.
We truly wish that this helps someone.
Apologies for the shaky footage; recorded this on my cellphone.
