Jack up one wheel, release parking brake. If cdl is engaged the wheel can not be spun by hand. If the wheel spins freely by hand then cdl is not engaged.

engage cdl
jack the front wheels up
spin them by hand

or something like that

I agree, only need to jack up one. Any one will do

But only if your transmission or transfer case is in neutral, otherwise you'll be none the wiser.

The vital piece of missing information

Most common issue with retrofitted cdl linkage and no warning is not that it doesnt lock mechanically but the switch or it's circuit are the problem or missing, see if the switch on the top behind the spigot is well connected, if not find the connector and bridge the pins or give direct earth to the black/blue traced wire....if you got warning this way you need a new swicth or adjust the present one... it's important to get the proper switch cos there are 2 types...if no warning with earthed circuit the problem is with the wiring, if you don't find the plug you might need to route a wire untill a connector under the console and we'll speak then

Helpfull as always thanks to all.

i will see if i can solve it tomorrow

Correct me if I'm wrong.... But are you sure the internals are in the TC? I think there are a couple years in the middle of the run that didn't have the internal bits in the TC ( I'm just learning about D2's)
