Spare 12v inside cabin
Fancy myself an under seat subwoofer. It's only a little lad (160w) and comes with a 10a fuse.
Seems overkill going back to the battery for that and going through the bulkhead. Any 12v distribution blocks or spare fuse box entries I could piggyback on to? |

940: Trailer electrical connection
Most probably your car is prewired for a trailer. If you locate connector D5 for the tow bar electrics, you can use the 12V accessory wire (pin 9). This feed is powered via a 30A fuse (nr. 3). You can probably find connector D5 somewhere at the NS rear wheel arch. Pin 10 of this connector is a switched 12V feed from fuse no. 8 (15A).
At the front there should also be two 4 pole accessory connectors D19 & D20 left of the glove box compartment. Pin 4 of either connectors (green red wire) is an unfused 12V feed directly from the battery. Pin 2 (orange wire) of D19 is a switched 12V feed via 15A fuse no. 14. This is all for a 940. I do'nt know for a 960, but I guess the trailer connection will be there as well. |

Perfect thank you. I do actually think the car has a second towbar socket that is never used, I assume that's a beefy aux power one so should be able to trace that to the bin. THANKS!

Its seems a pity to use this feed. This could be used as is to supply a 12v tyre inflator or even charge the battery ,or similar. This seems to be more work than taking another feed via a relay direct from the battery. As I recall there are plenty of'openings' through the firewall on these vehicles.
FWIW!! |
