−	~~''Needs~~ to be ~~investigated and written here~~ ...~~'''~~	+	==== Solution 1 - installation of a custom "2WD-L" switch ====
		+
		+
		+	The following solution has been mentioned by forum member "Riccy" as tested and working:
		+	# Fit an inline switch on the wires to the solenoid for the front vacuum hub heads.
		+	#* Those are the white wires at under the battery that everyone shorts out when they fit manual hubs.
		+	# Wire that switch so that it shorts out the wires when turned ON.
		+
		+
		+	How to operate it:
		+	# When you are in the ordinary 2WD-H transmission mode and want to engage 2WD-L transmission mode, turn that switch ON just before using the usual procedure of shifting into 4WD-L by using the transmission push-buttons.
		+	# Then switch from 2WD-H to 4WD-L transmission mode as you normally would.
		+	#* The consequence of having those wires shorted is that the 4WD controller will assume that the front vacuum wheel hubs heads had already done their job before even attempting to apply vacuum to them.
		+	# Therefore, the 4WD controller will then just shift the transfer box into 4WD-L mode accordingly, but without the front wheel hub heads being engaged.
		+	#* This means that the transfer box will be in low range gearing mode, the front propeller shaft will be connected to it, but the front wheels will be disconnected from the drive line.
		+	#** This way the 4WD-L transmission mode will effectively behave as a proper 2WD-L transmission mode.
		+
		+
		+	The procedure of shifting from 4WD-L (2WD-L) back to 2WD-H is the reverse from the above (i.e. finish the usual shifting procedure, then turn the custom switch OFF).
