It's more than just the wiring. You need the blow motor module, the vacuum solenoid, temperature valves and actuators. If you're removing the dashboard to do some work, it's not too bad. But you do have to remove the dashboard to get to the parts you need. Definitely not an hour job of soldering a few wires. I used compnine to find the differences because I was changing my I/P wiring harness. I'm out of work, so I had the time to do it.
