I currently have unheated, manual seats, and a very meager harness. I'm switching in leather power sports seats with heat and adjustable lumbar support.
It will be a TON more work and cost to install complete factory harnesses. If you want to be lazy go and find a dealer that will work with you to install and code the upgrade.
If you want to keep the costs to a reasonable level be prepared to DIY and
