Not that I'm aware of.
Most of the wiring will go between the passenger and driver seat. Here is some instructions from TFC
Heated seats are very easy to install, just wire up the left and right seats, supply power for the heaters and plug the seats into the PCI bus system in order for it to communicate with the Body Control Module.
I have indicated on the enclosed wiring pin-outs, which wires need to be connected from the left seat to the right seat. They both need to be hooked together, as the Heated Seat Memory Module has to “see” the passenger seat, otherwise it will go into a default “no operation”.
The left seat plug has a large number of wires that do not need to be connected.
These are for the memory outside mirrors
The main seat power wires that supply movement also provide the ground circuit for the heated portion, so there is no need, or any provision to add a separate ground.
The power wire for the heating elements is the dark blue with the white tracer.
The factory runs the drivers side up along the sill to the junction block; the passenger side is run up the right sill, and goes through the dash harness and is joined to the driver’s side.
You can simply splice the right side into the left side, and run it across with the other wiring.
In the junction block, the DB/W is plugged into the C7 connector, which is “natural” coloured (commonly looks white), and is put into the empty slot that is
UNDER the red wire, and BESIDE the black/yellow wire.
In all cases it should be open with no wire there, since that is a dedicated slot for the HSMM power.
The PCI bus wire is used to tell the seat module whether or not the car is in gear, so as to disable the memory portion, this wire must be connected, or again the system will not work.
It also has a dedicated slot, in the Body control module #4 plug, which is blue, and goes into the #9 slot, which is UNDER the tan/red, and BESIDE the tan/red wires
