For those that have power driver seat or heated only front seats and react to check if they have the wiring to support heated & vented seats with power adjust at both.
Need to see the truck side wiring for the 2 connectors under the driver seat (i400 yel & i401 grey) and the passenger side i420 (yel) where I can clearly see both rows of wires at back of the female connectors .... NOT THE SEAT SIDE.
driver side i400 (yel) & i401 (gry)
* If i400 has 3 pink & red wires at 1,7,8 you have needed power

Passenger side i420
If i420 has pins 1-5 = heated/vented
14,15,21 are seat adj & inverter supply
