That's great experience!!
I wish vehicles were still this simple...
I'm trying to figure out the wiring.
Looking at wiring diagrams for dsc57 on prefacelift vs dxc8 on facelifted 4.8 x5. All the wiring seems to be different...
I don't know if I still wanna do this project if I need to spend a full week on tearing the interior apart to fully replace the body wiring harnesses hahaha
