arb locker switches

Great thread. I could never argue convenience or vanity over versatility when were talking about wheeling.
Examples of front locked only are spot on. A driver can always break stuff...that's no reason not to have more control.

So if you have the factory rear locker, do you have to do any tricks with the wiring to fool it that that the rear is locked when you install a front only ARB?

You don't have to "fool" anything. The ARB Front Locker has nothing to do with the Toyota Rear. Simply lock the Front ARB via the ARB switch and you're done. If you want to lock the rear then lock the rear.

You never want to lock the front without the rear, surefire way to break something up front, this is why ARB harness is wired so the rear has to be engaged for the front to work.

Technically speaking you may or may not be correct (technically you are correct... given the differences in front/rear diff comparisons...hi/low pinion and smaller R&P up front...). Anything can be broken with enough skinny pedal at the wrong time. But with regard to how torque is handled front side of the 100-Series IFS...locking the front on steep straight up hill climbs/obstacles works better.

With our IFS you get torque induced suspension lift especially noticeable on steep climbs...whereas my 80-Series friends don't. That is one reason the 100 feels so ass heavy on those types of climbs/obstacles!

My front ARB locks up significantly quicker than the OEM rear e-locker...and it releases quicker so in technical sections where I need to cycle a locker on/off the front is my go to tool very often. Reason enough.

There are situations where I use both or just the rear but on steep climbs where I don't need both locked the front gets the nod.

Thanks, but I think you may have misunderstood me. Your answer is probably still the same though.

Previously in this thread someone mentioned that the ARB wiring was such that you HAD to have the rear locked before the front would lock (maybe I misunderstood). My questions was do you have to do anything to the ARB wiring to make it think an ARB rear is installed and locked, so that it will then lock the front.

I think I likely just misunderstood the previous comment.

If you have the original Toyota locker in the rear axle and you add an ARB Locker to the front axle you don't have to do anything, you don't even need the rear locker switch. Just leave the connector for the rear empty. As soon you switch the compressor on and the front locker switch the axle will lock. Different would be if you have also a rear ARB locker and connected to the rear ARB locker switch, then the front locker only locks after the rear switch is on.

In my 100 I have the OEM locker in the rear axle and the ARB locker added to the front axle. I can now use both independently.

I have added a rear ARB locker switch to a later date but it was purely to fill the gap and also looks better.
