Gen 4 Heated Seats retrofit

On or off is fine with me. I was going to use a second base heater in the backrest. of the drivers seat.

I'm not a passenger in my own car so don't need to do both.

I can't answer your question directly but can tell you that the euro spec LCV that I have has the heated seats fitted.

I find it difficult to believe Suzuki changed the loom completely for the UK spec, more likely just deleted a sub loom as you suspect. The fuse box might give you a clue...

I have dug around a fair bit and found a great post on Reddit by a user called: Alarmed-cumin and he posted a fair bit of detail that I will pop here if that is ok.

He has looked at it and has worked out the following:You're after pins 9 and 10 on the big 37 pin connector which is the upper of the two connectors facing the rear of the car. Sumitomo 050 pins are what those connectors use (I think).There's obviously nothing in those pins out in the Australian delivered ones, but you can disassemble the wiring connector and put the appropriate pins in and then you should have power delivered via the S/H fuse which should be accessory switched power.Pin 9 would then be routed to the driver side switch power input, pin 10 to the passengers side switch input.Also need to pull out an illumination wire (red on the dash switches is the +ve for illumination and -ve is purple, which is how you get the illumination backlights for the switches to dim properly with the dash units).Power out to the seat heater element goes to the seat element per side (obvs), need to also ground the switch for the illumination for the 'on' position.Basically for the switches pin 1 is ground for the 'on' light, pin 2 is the dimmable ground side for illumination of the backlight of the switches, pin 3 unused, pin 4 out to seat heater element power, pin 5 is power in from the fuse/junction box, pin 6 is dash illumination +ve in.Thanks to Alarmed-Cumin for the info, I will be checking that out if there is no "sub loom".

I just need someone with a Jimny with heated seats to look at the loom and then I know which way this needs to go.
