Some want to be able to use low range on a steep driveway or boat ramp, some say it's more fun to wheel with the center open till you need to lock it, etc...
Yes, the 7-pin mod disables this and allows the CDL to operated independently of the transfer case with the factory switch.
The CDL light should come on when you shift into low range if the truck hasn't been modified from factory.
OK boys and girls, once again we're confusing the issue. Please pay attention to the thread.
The OP is asking about an FJ80, not an FZJ80. An FJ80 does NOT have an electronically controlled transmission. An FJ80 does NOT have ABS. Therefore the pin 7 modification buys you nothing on an FJ80.
It does in factory form.
You are correct sir. All that sensor does is lock the center in low range. With it disconnected you have manual control of the CDL in both low and high range.
This is true for all fulltime 4WD 80 Series.
I just saw this post. What you're feeling is the gear reduction of low range. Low speed/high torque. Has nothing to do with the pin 7 mod or locking the CDL, just a function of being in low range.
...
Bingo.
How so
If all the 7 pin mod does is prevent the CDL from locking automatically when shifting into Low Range so you have full control over it with use of the button, then that buys a lot in my book
Being able to make tight turns in Low Range (CDL off) without binding up the drive train is well worth it IMHO
It actually makes a huge difference when you're trying to park 10,000 lbs worth of power boat in a tiny space behind the shop

He's just saying it's easier to unplug the switch on the t-case.
I knew about both methods, but chose to do the Pin 7 mod. Much cleaner than having a connector dangling around or zip tying it to something.
Nope he's saying no need for the 7 pin mod on an fj80. Different from a fzj80

We really need to address the lack of reading comprehension in this forum.
Please read post #3 and #8 and open your eyes this time.
No, he's saying that the pin 7 mod and unplugging the connector in the t-case do the exact same thing on an FJ80, it's just easier to unplug the switch than it is to do the pin 7 mod.

Good info thanks.
I've been meaning to disable the CDL in low but haven't gotten around to it.
So much easier to unplug the sensor on the t-case.
First order of business was to go try a hill I normally avoid.
Scoots right up it now. 30 MPH @ 3000 RPM instead of 5 MPH @ 5000 RPM.
