I have a new 2015 Ranger 900 XP Northstar edition, somewhere I got the idea the 4 wheel doesn't engage in reverse. Can the front differential be activated using a toggle switch, I think its a ground activated engauge.

If it does not work in reverse, your gear sensor may be defective. Assuming that Polaris hasn't changed the design from the older models, if it does not sense that it's in gear, AWD will not engage. Is your gauge showing that it's in reverse?

So your goal is to lock the front diff but leave the rear unlocked?

You could wire it so that the coil is constantly energized, but it will still not be truly "engaged" until the rear wheels start to spin. That's just the nature of the beast with an overrun hilliard system.

True, I visited them several weeks ago, saw them being built and a good understanding of them.

Putting in AWD allows it go into AWD does not make it go, It is a mechanical difference in ground speed and shaft speed. Meaning going down a straight flat road everything is turning the same, the sec the input shaft turns faster due to rear wheel spin then the front locks, only takes about a 1/4 turn.
