Ok, I'm making headway... a lot of things are different from the MS/MX codebase. I've got the data loaded, now to create a modified interface for Model 3. Not sure I can or want to integrate it into the MS/MX interface since there are so few options for Model 3. Just for example, here is a entire option code list for one inventory Model 3 unit:
APBS,DV2W,IN3BB,PPMR,PRM30,SC04,W38B,MT301
That's it! Compare that to an MS/MX option code list.
So far I can load about 200 Model 3s, but the code is still running. Unfortunately, we have guests coming over shortly for the holiday, and I have to step away for more "domestic" tasks.
Not sure the wife would appreciate me retreating to the office for the rest of the day. I hope to have something workable online later today or tomorrow.
