I have spent some time now reading the amazingly valuable discussions on this and other VW forums. Incredible how much I have learned about my 35-year-old Convertible purchased new in Germany. Appreciate the info -- ALL of it.
Here is my specific problem (challenge):
I want to use a new GPS speedometer and forever forget the original mech cable thing. The new speedo has nicely built in turn signal (L and R) indicator lights and a hi-beam indicator.
The issue I am facing is how to connect from the existing wiring to enable using the L and R on the new gauge.
--- could I simply splice one of the communication connections (for example, from the turns switch on column) ??
--- could I split the incoming to dash wire in some fashion to have L and R indicators work instead of one green bulb on dash?
--- could I splice the actual switched power wires to the 4 signal lights and have the new speedo pick up the pulsed signal there?
I am almost finished with successfully waving good-bye to the rapidly dying blue foil circuit serving the instrument panel. A new tach was easy. With a solution to the R-L turns "pulse" and new external water temp and oil pressure gauges, I will be updated and happily driving my dear Convertible for another ----- years.
If anyone has already worked this out, please refer me to that information (Briano, specific thanks to you for your dedication to the members over the years).
