Seat swap question 2003 Z66 with 2005 2500

[vicca]

Will my seats from 2003 Z66 WBH fit my newer 2005 Cladded 2005 LS?  I'd need to swap door panel controls too to get heated seat controls. Will the heater harness be installed in the 2005 if the option was not added?  The 2005 has plain cloth seats, Z66 has heated leather.
Thanks.

Do you have side airbags in the seats

Not sure.  The Z66 might have them.  Is there an easy way to tell?

Look on the outboard side of the seat back facing the door for the seat mounted air bag.

This picture is from my 2004 EXT.

My 2003 Avalanche Z-66 has them in the same location.

I don't think the LS will have the harnesses needed for the power and heated seats.

That's true, way too much work considering aftermarket seat heater run about 30 bucks.
