Kevin. Posted July 14, 2013 Report Share Posted July 14, 2013 been looking into adding rear seat heaters to my 850R seats, are these the stock connectors for them? I'd love to see input from someone with stock rear heated seats so I have an idea of what I need to do Link to comment Share on other sites More sharing options...
burnout8488 Posted July 14, 2013 Report Share Posted July 14, 2013 Yes they are! Your car looks like it is prewired. There should be two plugs per side, one for each seat bottom and seat back. Do you have wiring for the switches in the center console as well? This is an S70 harness for the single button rear heated seats, yours is probably separated into the individual sides: Link to comment Share on other sites More sharing options...
Kevin. Posted July 14, 2013 Author Report Share Posted July 14, 2013 I haven't pulled the center console yet to see, but I found the part numbers for the seat heaters for the rear seats as well as the switch part numbers do you have pics of the bottom of the cushion and the wiring for the center console? here are all the part numbers for everything http://www.tascaparts.com/parts/1996/VOLVO/850/?siteid=213668&vehicleid=1433983§ion=ELECTRICAL&group=BODY%20ELECTRICAL&subgroup=HEATED%20SEATS Link to comment Share on other sites More sharing options...
burnout8488 Posted July 14, 2013 Report Share Posted July 14, 2013 I have a lot of pics, but they're all S70 specific. Not sure how the 850 center console wiring differs since there are two switches. The pads are sold out worldwide, I tried ordering them from Tasca a year ago. You'll have to find a junkyard 850 or S70 with rear heated seats to get the pads. Same story with the antenna down switch, you can order them but Tasca can't get them. After speaking with a rep for 30 minutes they finally told me that no dealership has them, and they aren't in production anymore. Whole system: The far left yellow connector above is the connector for the switch. The relay clips on to a piece of plastic in the center console near the e-brake trim I believe.

Kevin. Posted July 14, 2013 Author Report Share Posted July 14, 2013 hm, Tasca lists part numbers for all of them I will try ordering from my local dealer and see what happens Link to comment Share on other sites More sharing options...
burnout8488 Posted July 14, 2013 Report Share Posted July 14, 2013 The only thing that might differ is the fact that you're an 850, but being older than an S70 I would be very surprised if pads still exist out there for it. Link to comment Share on other sites More sharing options...
Kevin. Posted July 14, 2013 Author Report Share Posted July 14, 2013 from what I have heard from other guys on the boards, they are still available Link to comment Share on other sites More sharing options...
Keep Calm Chive On Posted July 14, 2013 Report Share Posted July 14, 2013 I wanted to get rear heated seats but the back trim piece in the rear I haven't ever seen in a wood trim Link to comment Share on other sites More sharing options...
Kevin. Posted July 14, 2013 Author Report Share Posted July 14, 2013 burnout, you found the elements and added them into your existing seats? how hard was that? I'm guessing you had to add relays and fuses as well Link to comment Share on other sites More sharing options...
(n)A-GAME Posted July 15, 2013 Report Share Posted July 15, 2013 You know it would be 1000X easier, not to mention cheaper, to just wire in generic seat heating pads, right? If you want to get real fancy and use an OEM switch, go for it. Link to comment Share on other sites More sharing options...
burnout8488 Posted July 15, 2013 Report Share Posted July 15, 2013 That, or just find any junked P80 with rear heated seats, even the XC ones will work. I don't know if this matters, but the wiring for my S70 put the pads in series, with the circuit ending at a ground point on the chassis. Only one 12V wire powered the entire rear seat. Aftermarket pads may or may not jive with this setup? Not sure. The easiest way to go about this is with all OE parts, since they fit perfectly in the seats and the wiring is also meant to pop right into our cars.

Kevin. Posted July 15, 2013 Author Report Share Posted July 15, 2013 I dont think it will matter since if I use X70 ones or not Link to comment Share on other sites More sharing options...
burnout8488 Posted July 15, 2013 Report Share Posted July 15, 2013 I wanted to get rear heated seats but the back trim piece in the rear I haven't ever seen in a wood trim Shit, I had that for sale last year. I was surprised to even find it... a wood rear trim panel with the rear heated seat button cutout. Must be super rare. burnout, you found the elements and added them into your existing seats? how hard was that? I'm guessing you had to add relays and fuses as well I cut the leather off the junkyard car's rear seats, and gently peeled the heating elements off of the foam. Installation onto my seats was just a matter of disconnecting the hog rings, placing the elements, and using upholstery spray glue to hold them in place. There are even little holes in the seats for the wires to pass through, check it out. No fuses or relays other than the relay that is part of the center console harness, I did the install using all OE parts. The parts you see in the picture above just pop right in. The rear heated seats are powered off of a wire in the center console harness. You do need a center console harness specific to a vehicle with rear heated seats though. I found an S70 in the yard equipped with this, and stripped every component from it involved with the system. If you take your time you can do this exactly how the car would have come out of the factory with this option installed. Takes some time but totally worth it for the OE functionality in my opinion.

Kevin. Posted July 15, 2013 Author Report Share Posted July 15, 2013 yea, I may just pull everything if I find one and see what matches up oh I see it now, there is a seperate harness that goes into the center console for this....hmmmm Link to comment Share on other sites More sharing options...
