Just a reminder I am using the entire circuit from the 80 series harness with the oem transmission relay to operate the center diff lock. The hazard pull switch I am using is from a late 70s to early 80s Toyota Hilux. I believe you should be able to use what ever hazard switch you have. The switch plug has 6 pins but I am only using three of them. In the off position the switch disengages the CDL and when pulled it activates the CDL. The switch wiring for your 100 series looks almost the same as the diagram for my 80 harness, given that is true you would want to do the following.
First I don't know what switch you are using but you need to identify the two pins that provide continuity when close and when open.
Connect the Red/Blue from the switch I circled on your diagram to the constant power terminal on your switch.
Connect the Black wire from the switch I circled on your diagram to the switch terminal that has current with the switch pushed in to disengage the CDL
Connect the Black/Red wire from the switch I circled on your diagram to the switch terminal that has current when the switch is pulled and it should engage the CDL
It is possible I reversed the Black and Black red wires, so switch them if needed.
I realize this makes sense to me but may not be clear for you, so let me know if it needs further explanation.
