Default Hidden relays and other components

In a recent search for the turn signal/flasher relay on my 1995 C2, I found a couple of other relays that are not in the front boot fuse/relay panel, nor the one in the engine bay.

Inside dash, left side, pull instruments to access:

964 618 103 00, instruments brightness control, smaller of two, toward front.

928 618 102 03, seat belt warning, taller one, toward rear.

Inside center console, access panel on R side:

1H0-953-227-M5206, turn signal/flasher relay.

Sometimes the shop manuals are a bit sketchy on where to find things. It would be helpful to build a list of components that are in unusual locations--can anyone add to this list?

They must have changed the location of the turn signal/flasher relay relay, as my '97's is in the trunk compartment way behind the driver's side hood hinge. Prominently marked "VW".

While performing a Google search for the above part number (I wanted to see the circuit diagram on the component case *), I came across your thread. Good info, Bob!

* as far as the Control Unit Instrument Light module goes, the electrical wiring diagrams show a transistor symbol indicating to me it is a solid state device.

Bob, components can be found using Sheet 15 - Construction Components and looking up Control Unit Instrument Light, located at coordinates 7bQ for a LHD 1995 vehicle (96 and up, they are in the front fuse panel). You then look those up on the vehicle outline coordinates on the same sheet. In this case near the driver's side mirror and gas cap areas....or as you pointed out, behind the instrument panel.

Porsche's electrical wiring diagrams consist of 4 sets of wiring diagrams: 95 (early 1995), 95/2 (late 1995), 96 and 97-98.
