2005 silverado heated seats 4806 and dball2

Hey gang! I am finishing up installing the 4806 remote start and DBALL2 interface. All is going well except for a strange issue with heated seats. On sending a start, the truck fires right up. Today it is cold here and I noticed that the heated seat lites are on. Great, but only the seat bottoms are lit up. The lite for the seat back are off. Tried to poke it manually, and both light up that way. Interested to see what input you may have. I did wire 2nd acc brown thru a relay and the orange wire from pin 23 on the rs unit. Working mainly from Kreg357's 5706 post here. Thanks !!

Oh, - forgot to add - diesel truck

Update: Oddly enough, the seats are working correctly, it is just the lights on the control that are different. Today was the first decently cold day, and I remote started. On getting in the truck, seat back and bottom both on high and toasty warm.   Lights still show bottom only on high.    I am ordering a bit writer to take a look that way, but it is working nonetheless. Thanks all!
