If your 91 FJ80 is the same as US-spec 91 FJ80's the center is only locked when you press the CDL button. As I stated above, on a 91-92 the center diff is only locked when the center diff button is pressed....regardless of the position of the transfer case lever. On a 93+ it would automatically lock when placed in the 4L position.
It's a "Pin 7 Mod" on an FZJ80. The FJ80 doesn't have ABS and the transmission is not electronically controlled. Simply pulling the connector on top of the transfer is all that's needed.
That's correct! We are so much part of the US (and proud of it) that we just had a quarter minted as part of the 50 states collection, this means the Land Cruisers we get here, must be U.S.A. specs.
In aus. I was told the early 80's cdl was vacuum operated and 94 ish they changed to electronic could this be true?. I know my brothers 97 80 come std with a cdl button and as said above if you select low range with out touching the button it does automatically go cdl
No. The FJ62 had vacuum switches to switch between 2WD and 4WD. AFAIK, no 80 Series has this. If the vehicle has a center diff this assumes full time 4WD. All CDLs were electronic.
That's because 93+ NA models came with a viscous coupler in the driveline, instead of a manual switch to lock the centre diff. The viscous coupler is kind of like a limited-slip differential, but for the transfer case instead of an axle.
I have a 1994 no center diff lock swith. I'm planning to install it. can somebody help.? I already have the magic push in center diff lock switch. ( from another lc)
I have a couple of questions..WILL it work? is it just a matter of plugging it?
please help/

Yes. The wiring is in place for the center diff lock switch. Plug and play. When you locate the wiring behind the switch blank the plug will have foam wrapped around it, just remove and plug it in.
The Center Diff Lock switch will give you manual control over the locking of the standard center diff lock. Stock US spec 80-Series have an automatic center diff lock that engages when the transfer case is put into LOW range, and unlocked when the transfer case is put into HIGH range. The switch simply gives you manual control over this standard function.
I recommend doing the pin-7 mod in conjunction with the installation of the CDL switch.
I think a little clarification is need, lets see if this helps?
Driving along in in a straight line high gear you car is delivering drive to all four wheels.
When you go around corners the centre differential allows the front and rear propshafts to spin at different rates so preventing tyre scrub as you corner.
When you shift the transfer lever in LO the centre differential locks and the speeds of both propshafts remain synched. Now this can be a PITA if for example you are trying to move a caravan or trailer into position using the low range which helps with slow movements however, if you are trying to do this on a high traction surface your transmission will 'wind up' putting strain on all related components and makes maneuvering difficult.
The CDL switch allows you to engage the centre differential lock whilst in high gear and the pin 7 mod allows you to decide if you need the centre differential lock or not in LO.
Why Toyota rigged it this way is anyones guess, the Discovery CDL can be engaged in any range at any speed.
