12s wiring on an 850

[myshed]

I've scanned this forum, but have not found any info, so apologies if subject already covered.
Just picked up an 850/2.5/20v estate with a single (12n) trailer socket fitted. Just want to add a 12s socket. I'm aware of the pin usage, but am looking for advice/others experiences of fitting this - which relays, where to locate, best cable routes, WARNINGS. . . and that kind of stuff.
Anyone help?

Thanks, Mike.
It's certainly the clearest diagram I've seen.
Unfortunately, though, it doesn't state what relays might be needed. For example, to enable van battery charging/fridge operating only when car running; what precautions might be needed to ensure vehicle electronics are not blown; that the bulb failure circuits are not compromised.
I sometimes regret parting company with my 240GLT estate (quite a few years back!) - this sort of stuff was trivial!!

Hi myshed. You need a splitcharge relay.fitted near the battery. You can feed the wires through the rubber bung in the bulkhead then run it along under the edging of the door frame then along past rear seats over wheel arch. A piece of wire will help here.
Your caravan reversing lights will have to go to the yellow wire on the s socket.
Give a ring if stuck. Have wired up about 6/7 cars.

Hi perhaps i am lazy but when I did mine Volvo did a fitting kit and loom the wiring running through the vents at the side of the rear bumper
