That is very helpful! It does have the switch on the dash, so that is solved. Thanks tclederman!
Jim, as far as shifting the axle goes, is it more like a transfer case high/low on a newer half ton pickup? What i mean by that is you pick either high or low range depending on the job and have to be mostly stationary to shift the axle up or down? or can you shift through the low range and while moving shift into high range?
