There's a couple guys that have done the digital HVAC system but I haven't heard of anyone doing a full harness. But Honestly I don't seeing it being that hard. More time consuming than anything. Just make sure you take pix of everything you take apart. Label what bolts/nuts go where. And while you have the dash out you might wanna throw some vibration dampener on the firewall. I know I would if I had the dash out.
