My AC evap is out, and has been since 2017. I don’t have to have it. Top comes off in Apr/May and goes back on in Sept/Oct. The heater core you can smell, so I was told it’s leaking, but it still heats, and has been like this since I got it in 2016. I just thought while I’m there fix them, but it’s not required.
The cooler I’ll have to figure out. I can do the cooler before and figure out mounting. I can also get a temp gauge brazed into the pan beforehand. It’s all just another thing to figure out. Thanks for the B&M tip.
I read that 05-06 X models don’t have the OD connector, and I pulled the center part of the dash and didn’t find it.
To add some clarity, there are two under dash harnesses. You don't replace the main one that goes to the instrument cluster. It is the dash controls part that gets replaced.
I think they are differentiated by dash and body harness.
