    heated seat plug wiring questions

    At the heated seat plug, GP seems to be power and B is ground.  There are 4 wires that go to the instrument cluster for indication?  Or maybe Triumph uses a dual element seat heater and the 4 wires are for the seat heat?  Just seems odd to me to have the power coming through the instrument cluster.  My questions are as follows.  GP only sees voltage when my heated grips are on, the other 4 have 7.4 volts present.  Thoughts?  Has anyone else worked on this?

    Hard to get good pictures or any schematics on what Triumph did, but I saw one that looks like the seat has a 2 pin plug.  In light of that, perhaps Triumph is using KS and GU for one seat for indication and splitting the GP wire with them, common ground and KY and GN for the other seat hi/lo indication splitting the GP wire with those and common ground.  Thoughts anyone?  Anyone with heated seats willing to donate some time and ohm out the harness?

    Not trying to be confusing, I am using Triumphs color designation for the wires.

    GP - Green/Purple tracer (Power from heated accessory relay) - Pin 1 on heated seat plug
    B - Black  (Obviously ground) - Pin 2 on heated seat plug
    KS - Pink/Grey tracer (Pin A15 on gauge cluster) - Pin 6 on heated seat plug
    GU - Green/Blue tracer (pin A14 on gauge cluster) - Pin 4 on heated seat plug
    KY - Pink/Yellow tracer (Pin A13 on gauge cluster) - Pin 3 on heated seat plug
    GN - Green/Brown tracer (Pin A8 on gauge cluster) - Pin 5 on heated seat plug

    I don't understand exactly what you want to do or look at or if something isn't working with the heated seats.

    I don't have an electrical schematic at hand, the voltages should go from the ignition key, fuses, heated seat push buttons, and heated relays.

    Yes, it is possible that four of the cables go to the instrument panel.

    Keep in mind to have heated front and rear seats. Just to display the icon with its functions on the instrument panel, it requires four wires to display the following information:

    -High heater for front seat
    -Low heating for front seat
    -High heater for rear seat
    -Low heated rear seat
    Only motorcyclists know why dogs stick their head out the car window.

    I just had a look at the Wiring Diagram and my Trophy for you and determined the following :

    Main Trophy Harness Heated Seat Socket :

    1 - G/P - Power supply from Fuse No 1 of the Front Fuse Box
    2 - B    - Ground
    3 - K/Y - to Pin A13 of Main ECM
    4 - G/U - to Pin A14 of Main ECM
    5 - G/N - to Pin A8 of Main ECM
    6 - K/S - to Pin A15 of Main ECM

    I only have the Heated Rider seat fitted with no Heated Pillion Seat.
    In this case the Heated Rider Seat sub harness plugs directly into the Main Heated Seat Socket,
    and has only 4 Pins within its plug.

    If the Heated Pillion Seat Sub Harness is present, it has six pins in the Plug that connect into
    the Main Heated Seat Socket, and also has an additional Socket within this Sub Harness
    that the Heated Rider Seat Harness plugs into.


    Heated Rider Seat Sub Harness - Plug connected to Main Heated Seat Socket :

    G/P - From Pin 1 of the Main Heated Seat Socket, connects to the centre Pin of the Rider Switch.
    B    - to Heated Rider Seat Socket
    K/Y - to Heated Rider Seat Socket
    G/U - to Heated Rider Seat Socket

    Heated Rider Seat Socket

    G/R - From Rider Heated Seat Switch
    G    - From Rider Heated Seat Switch
    B    - From Pin 2 of Main Heated Seats Socket
    K/Y - From Pin 3 of Main Heated Seats Socket
    G/U - From Pin 4 of Main Heated Seats Socket.


    I haven't started the engine ( required for the Heated Seats and Grips to work )
    to determine which of the two Heated Rider Switch Outputs ( G/R and G ),
    control the Low or High seat settings.

    I imagine that the connections from Pins 3 and 4 ( K/Y and G/U ) of the Main Heated Seats Socket,
    that go to the Main Trophy ECM are used to switch ON and OFF the diffferent Icons, displayed on the Instrument Panel, for the Low and High heat settings.

    I believe that if the Heated Pillion Seat is installed, Pins 5 and 6 ( G/N and K/S ) of the Main Heated
    Seats Socket would be similarly "used" by the Main Trophy ECM for the Pillion Seat Instrument Panel Icons.

    I hope that helps to explain the system, here's a Diagram to make it a little clearer :

    Coconut, I don’t suppose you have a link to the subharness installation instructions, red M(John)!has previously found, but no harm trying to get a link for others also to follow. Thanks Kev

    It's contained within the complete Instructions for fitting both Heated Seats.

    If you go here : Triumph Instructions.com

    ... then Enter this Part Number : A9708259, and lick the "Search" button,
    it will return an entry for "HEATED RIDER SEAT (3D NET)"

    Just click on the Flag alongside the entry, for the Language you require,
    and the Instructions will be downloaded.  :028:

    In simpler Terms, The Pillion Sub Harness has 4 connectors.
    ( It is drawn incorrectly in the Triumph Instructions, with only 3 connectors !  :027: )

    One is a Plug that connects into a Socket of the Trophy Main Wiring Harness.
    One is a Socket that the Rider Heated Seat Harness Plugs into.
    One is a Socket that the Pillion Seat Plugs into.
    One is a small socket for the Pillion Heated Seat Switch.

    The drawing in the Instructions, for the Heated Pillion Seat Sub Harness, should look like this :
