There is a plunger type switch that could be used for the Dash 4high and 4low lights, not required for operation but was available.
The dash lights get 12v with key on, the two wire switch is a Ground, one for 4high and the other 4low, and of course no light in 2WD
I believe the dash light wires at the 4x4 Module(not needed now) are the same colors as the wires on the Manual switch, so you just have to match them up.
Brown/white for low, and Grey for high, but could be light blue instead of grey
But as said not required, you just need to look down at the shifter to see where its at, lol.
You will need the VSS hooked up with the speedometer cable on 1994 and older
Parts for the 1350/1354 manual shift linkage are nonexistent so make sure you have all the parts before starting, or be prepared to make them yourself
