3 and 4 Speed Floor Shift Manual Gearboxes:

With age many of the switches are failing (some just dirty contacts inside switch).

Locate the switch and make sure it is functioning 100% before worrying about the wiring!

In most cases it will be a switch or switch adjustment issue!

Wiring in the old Holdens is pretty good (even old as it is), its quite often only the connector plugs that will let you down!

How did you go?
Hope you got it sorted o.k.?
