Does anyone know how the 4wd switch in a Dana 300 T-case is activated and where it is? I put a new tranny in my 85 CJ7 several months ago and during that process, I removed the shift lever from the transfer case to make it easier to remove from the vehicle. Ever since then the 4wd light in the instrument cluster does not work. The wire is connected, but I have not had the time to investigate further. I assume that grounding the wire will activate the light and that will tell me if that is working. Do I have to try adjusting the shift lever?
