jdub53 Posted January 7, 2023 Share Posted January 7, 2023 I just bought a pair of used Sargent heated seats for my '13 RT and am hoping for assistance in how they are supposed to connect to the OEM wiring harness. Below are pics of the connectors coming off of each seat; two wires for the rider's seat and four wires for the pillion which jives with both OEM seat connectors. If it's just as easy as me buying OEM connectors and splicing them onto the Sargent seat wires in place of what's already there, then I'm all set. The big unknown to me though is the extra wiring that was provided with the Sargent seats (pic below). This looks very homemade to me, includes a resistor, a cut-off 5 amp inline fuse, and has both seat connectors wired into the same harness. I find it hard to believe that Sargent would provide such an 'arrangement', unless this was provided/meant for an RT that didn't have OEM heated seats to begin with and was meant instead for direct connection to the battery. Thanks for any help. Link to comment
bruce2000ltc Posted January 7, 2023 Share Posted January 7, 2023 I think you're right, that harness is for an RT that didn't come with heated seats. I looked at the Sargent seat on my '13RT and the color of the wires on the Sargent seat match the the wire colors on the RT seat connection harnesses front and rear. Match color to color with connection plugs and you're good to go. 1 Link to comment

Because it appears I'll only need new connectors which will mate with my RT's heated seat wiring, does anyone know of an online source for such connectors? I may drop by my dealer next week to check there, but not confident they'll have these because it's likely not something they'd need to stock. Link to comment

Morning jdub53 You will need both the connectors & the terminals. You might be able to get the terminals from the BMW motorcycle dealer but you will probably have to take a sample in to show them (or know exactly what they look like) as they typically have no way to look them up by make & model. I seriously doubt they would have, or be able to source, the connectors. I have had very poor luck sourcing any stand alone connectors from a BMW motorcycle dealer as most are not in the parts manual & usually no stand-alone parts numbers. Same with on-line, if you can find a part number, or know EXACTLY what you are looking for looks like, then the with a LOT of research you might be able to match the connectors up to what you need. When it comes to BMW connectors & terminals I have had my best luck in sourcing them from a BMW car dealer. In most cases BMW doesn't source new or strange connectors for the motorcycle side as they try to use something that already exists in the BMW system. The problem with the BMW auto dealer approach is they won't be able to look them up by make, model or fitment so you need a friendly parts counter person that will take a little time to look through their connector stock & try to match them up for you. You will probably need to take a mate, or a sample, of the connectors that you need in with you then go into the BMW auto dealer at a very slow time at the parts counter. They most likely have a connector that will work, the problem is in finding it in their stock. Once the connectors are found then they can usually easily match the terminals needed to the connectors. Added: does the replacement Sargent heated seat have the built-in rear seat control switch? If not then you will have to figure something out for that also. 1 Link to comment
jdub53 Posted January 7, 2023 Author Share Posted January 7, 2023 Thanks for confirming what I suspected about finding the connectors/terminals at my BMW motorcycle dealership, @dirtrider. Good idea about trying a BMW car dealer though, and I'll give that a try at the dealer nearest me. I've decided first to just use the Sargent seats with no heat until I confirm I like the Sargent better than the OEM seat, which only started bothering me about 275 miles into a ride this past week. Thanks to the mild weather we've been having I should be able to get that done next week. If I find I like the Sargent better but can't find terminals and connectors compatible with the OEM plugs on the bike, the simplest thing is for me to just fit new, generic QD connectors to both the Sargent seats and the OEM bike wiring. I can then sell the OEM seats with their OEM connectors intact. The Sargent pillion seat does indeed have the three-position toggle switch as shown on the Sargent website (same place the rocker switch sits on the OEM seat). Link to comment
Mike279 Posted January 8, 2023 Share Posted January 8, 2023 I bought a Sargent seat a month ago for my 19RT and Sargent has the right connectors for it already installed. Might want to try them and see if they have ones for your bike. 1 Link to comment
jjpen Posted January 8, 2023 Share Posted January 8, 2023 I just put sargent heated seats on an r1200rt without heat from the factory. I used a dual remote controller for heated clothes from gerbing. I just spliced in the controller wires with posi-taps. It works great and I have infinate control instead hi and low. 2 Link to comment
Limecreek Posted January 8, 2023 Share Posted January 8, 2023 Repair Plug, 2-Pin - No 610619 - BMW-Motorrad (83300402344) $18. Worth a try. Most BMW dealers will order this for you or just use one of the online stores like MAX. 1 Link to comment

The pillion seat uses a four-pin plug though (I'm assuming two wires for power and two wires for the rider's info display to show which heat setting is selected). Any idea of the P/N for that plug?

That one is a little bit more expensive $52. Adapter Wire, Seat Heater, Pillion Seat - BMW-Motorrad (61127688147) 2005-2023 BMW-Motorrad - 61127688147 Again, you can order online through MaxBMW or through the online BMW Motorrad site. https://www.shopbmwmotorcycles.com/ Some splicing and soldering should get you what you need assuming the correct plug fitment. 1 Link to comment

Morning Limecreek Isn't that the adapter Cable between rear seat chassis connector & the rear seat connector? If so then it would have the chassis side connector & female connector pins in it? The OEM seat connector (one mounted on the seat) uses staggered male terminal pins. I suppose it could be hardwired to the rear seat then unplugged at the chassis when rear seat removal is necessary leaving the long pig tail on the seat. I have a - 61127688147 adapter cable in my shop somewhere but I will darned if I can find it at the moment to check to see if the chassis side connector will plug into the seat side connector. jdub53, you might try that with your stock adapter cable, see if the seat end will plug into the chassis end, if so then the $52.00 adapter chassis end can probably be used for your replacement seat end. $52.00 is a LOT to pay for a simple connector with terminals.

You may be right DR, I really don't know for sure. If it were me, for $52, I'd just wire up the passenger seat with a home made solution, but at least the BMW harness option gives jdub a few things to investigate. Link to comment
bruce2000ltc Posted January 8, 2023 Share Posted January 8, 2023 If you want BMW plugs just cut them off the original seats and splice them in...that's what I did. When I sell the bike I'll splice them back on to the original seats and sell the Sargent seats. Link to comment

jdub53 Posted January 9, 2023 Author Share Posted January 9, 2023 Thanks to all for your ideas and suggestions, but I now have my path figured out. While at an auto parts store today picking up something else I found these weatherproof connectors for a total of $14. Couldn't pass them up, and I can splice them on as easily as I could genuine BMW connectors. And in case I decide not to keep the Sargent seats, returning these will be much simpler than anything else. 1 Link to comment

Evening jdub53 If you splice the new ones in parallel as well as keep the old connectors then you can switch to either seat & not have to remove anything in the future. (just plug in correct connector for the seat) Link to comment
