I HAVE A 2002 2500HD DMAX EXTENDED CAB. I AM WANTING TO CHANGE FROM HALF POWER CLOTH SEATS TO FULL POWER AND HEATED LEATHER SEATS. I HAVE THE SEATS AND WAS WONDERING IF THIS IS POSSIBLE TO DO WITHOUT SWAPPING WIRING HARNESS IN THE WHOLE CAB? ALSO, WILL IT WORK WITHOUT REPROGRAMMING THE COMPUTER. THANKS

Power seats with heat come with a memory module. The memory module needs to talk over the vehicle comm bus. You are missing this content from your vehicle body harness. So the answer is yes it is possible, but no it won't be easy.

 

Your gonna need:

 

Cavity/pinout assignments for both driver and passenger seats.

The correct terminal and connector housing mating components to the seat. You will need electrical terminal crimp tool for varying gauge sizes form 3.0mm to 0.35mm.

Essentially, you will be rebuilding the connection from the seat to the body harness. The body-side connector you have is different than the one you need with full content seats.

 

Also, if you manage to complete the task, the module will not be on the vehicle communication buss and will not be capable of transmitting fault codes. You won'y be able to diagnose any issues.

 

Good luck...

THANKS FOR THE INFO. THE SEATS HAVE ABOUT A FOOT LONG PIGTAIL ON THEM

SO I CAN SEE THE WIRES I'M GOING TO NEED. MY BUDDY HAS AN HD WITH THE FULL POWER IN THEM SO I'M GOING TO BE DOING A LOT OF COMPARING.

THANKS AGAIN

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
