The time for summer road trips is coming near. I have thought of putting a cigarette lighter in the back of the center console so my daughter can plug in her headset without bothering me. Question: can I safely plug the wires to the lighter in the front of the dash without over heating? If not, where should I plug it in.
I am assuming that there will be room to put a lighter socket because the rear seats are not heated. 1995 854t.

Thanks all

I'm assuming most load. This would be radar detector in front lighter, DVD player in rear lighter. The S70's have the rear light option, and appears to be wired into the overload relay, and the same fuse. Further, the wiring diagram shows the fuse as both a 15 amp and a 20 amp. Both S70's I have here today do not have the rear cigarette lighter, of course. If you wish, I can attempt to fax a photostat to you, but it probably won't come through very well. I really don't see anything too terribly wrong with piggy-backing it into the ground and power of the other lighter, possibly wiring in a separate inline fuse, to be secured someplace hidden yet convenient, and putting in a 20 amp fuse in the main fuse block. The addition of an inline fuse is probably safety overkill since you have both the overload protection relay (with it's own ground) and the main fuse to save your fanny, but I'd most likely do it. If you take the time to wire it the way the S70 has it, plan on at least 4 hours, as it goes through several connectors, and ties into several fuses.

Depending on what you'll be plugging in, I wouldn't worry unless you & your daughter are both lighting up cigars at the same time.

My logic is: I think lighter is on a 20 (maybe 15) amp fuse. CD player, radar detector, cell phone and most car adaptors are mostly all 2 amps. Gives you lots of room to play with. Now if you are using one of those portable coolers powered by car adaptor you are talking a bigger draw - maybe 15+ amps - and you'll overload circuit. In any case the fuse for the cigarette lighter should protect you (have spares!) Just be sure to use good wires and don't run near moving parts (ie brake handle)

S70's have the option of a cigarette lighter for the back seat, and since the S70 and the 850 are basically the same animal, I'd probably look at the wiring schematic for the S70 to ascertain where to hook in your new accessory outlet. I have the wiring diagrams; I'll try to look at them tomorrow.
