2010 Lariat Interior Swap (Seat Wiring)
I have seen alot of posts regarding this topic but have yet to find a short and simple one, here she goes.
The seats are Power and heated with no memory coming out of a 2010 Lariat F350. They are going into a 2003 F250 Lariat, so my power wires had already been ran from factory. I had to run 1 more signal wire so to speak from the new upfitter switch, to each seat to trigger the heated function. This is the wiring as follows. I believe heavily in the K.I.S.S. process.
2010 WIRE HARNESS
YW/RD: Hot at all times (+)
WH/BU: Ground (-)
GN: Heated seat trigger(+)
GRY/RD: Hot at all times(+)
BK/VT: Ground (-)
the other 2 wires remaining in the 2010 Harness I did not use.
Passenger Seat is essentially the same thing, except the Heated seat trigger is GY/YE (+)
With those connected to the hot and ground leads from the factory 03 wiring, and the additional wire I ran, all functions work properly. I hope this helps some other member.
