Can someone please tell me which fuse/relay is for the interior lights of a '91GT? Thanks.

The interior relay on the later cars has the approx 30 second delay...that feature makes then less reliable and much more expensive. It is bottom row next to the last one on the right part # 928 618 225 01 about $150 for a new one....

Hilton, Thanks.


Jim, that's the one on my '88S4. I think on the '91S4/GT it's different, at least according to the chart from 928 Specialists.

On a '91 and later the interior light relay is embedded into the alarm & central locking module under the passenger (LHD) seat. The 928 specialists site is wrong about the alarm module location & part number (also for '92-95 GTS). You have to remove the seat to access this module - it is located under a metal screen - under center of the seat.

Thanks Alan for clarifying that .... It did appear to me when I looked at the wiring diagrams that Porsche had bundled a number of things into the Alarm Control...So no simple relay anymore !!
