Nice ride. Great job on the lowering.
Regarding the DIC, you can buy the switch separately and in your vehicle bezel it will have the switch mounts and the plug-n-play connector on the back side. You just need to cut out the area where the switch will mount. Or, you can buy a used bezel which already has the DIC mounted on it and swap out. This you can find on Ebay, or other used online parts site, if you’re lucky to find one. On Ebay, there just happens to be one (Silver trim) on sale and also includes a set of replacement AC vents. See link below.
You may also find other bezels in wood trim.
This is a similar set I got for my PPV, even though I didn’t need the AC vents, because I didn’t have time to do the cutting if I bought just the DIC switch. All I had to do was swap the bezels, plug the connector to the DIC, and it was good to go.
