ABS dash light

The Brown wire on transfer case is for an electric clutch inside the transfer case, it allows "shift on the fly" from 2WD to 4high and then back to 2WD
Clutch is used to engage the chain drive for front drive shaft
This was only used with Auto Hubs and electric shift up thru 2000

It was dropped in 2001 and up Rangers because front hubs were always locked so front drive shaft was always spinning at same RPMs as rear drive shaft, so no issue matching RPMs in transfer case

You can always try a new sensor

New sensor coming. The one bolt is easy enough, just hope it pops out of there without a fight.

So does spinning the front dif all the time cost gas? I leave my hubs locked since I use 4wd frequently. BTW I got 15 mpg last fill up, slight improvement. Still on the old sensors on driver side.

There have been a few tests on MPG using always locked front hubs on 4x4s and they show a 0.2 to 0.3 drop in MPG
I think AWD cars/SUVs are about the same

That little, no problem. I use my Ranger primarily to go back and forth to my cabin, 20 miles away, at least once a week, need 4wd for access.

As I mentioned, 4WL can be a bit finicky, sometimes need to drive it a bit to engage/disengage. If there’s a trick to it, I’m all ears..

New sensor installed today. ABS light out!

I’m going to miss that thing..
