Turf mode diff installed - How do I wire the switch?

I installed the turf mode diff and I am having a problem finding out how to wire up the switch and relay with out having the International ECM. Where can I find a wireing diagram for a ranger w/ turf mode that might help?

+1...it isn't as simple as just wiring up a switch..the solenoid doesn't work off of 12v..12v will toast it from what I understrand. AFAIK 34Ford is still working on having the electronics made that are needed to make it work properly with the US ECM. IIRC in the mean time he is running a manual actuator?

Not sure why Polaris makes this so hard. Plenty of people would like the option. Would be nice if the would just offer a kit for this.. Maybe even allow you to exchange your ECU for one that would work.

It says 12 v something/ 3v something..pm 34Ford..I gotta think if it were simple he would have done it..again he has consulted and Electrical Engineer..he even has a website on his turf mode mod..maybe he has missed something simple..it happens..but before this guy smokes his solenoid..wouldn't hurt to talk to 34Ford.

If that schematic is correct? That power supply / relay combo package they show looks like it would run everything the solenoid needs? 12V in and power for the solenoid out (whatever voltage that is). All you need to do is close a few grounds and the solenoid will energize. You need the power supply/ relay (shown in the schematic above) and the solenoid, I think that's the entire circuit? ECU sends a ground out, that should be easy to emulate with a switch and relay. I think the 12V pull and 3Volt hold is controlled by the power supply / relay package.

Hear ya HO...

I don't see 3v
Like to see the whole sticker, or at least copy down whats on it ,exactly as on the sticker.

But if ya think about it, no way its 3v or 3 v hold(never seen any automotive type solenoid that requires 2 different voltages to actuate and hold...nah, no way). Unless Polaris has a transformer some where to convert 12v to 3v because the ecu or speedometer cluster sure wont do that for the amperage required to pull in the plunger. No, its a simple 12v electromagnetic mechanical plunger assembly.

2 ways to wire it

Hard way

Buy the relay I posted above.
Go into the wire diagram for the international model and find what ecu wire connects to the relay.Connect it to relay.
Wire in new switch to relay, rear diff to relay, and power relay from a key switched power source.
This is all assuming the USA model even has this ecu wire...


Easy way

With this set-up you must come to a stop before switching diff in and out of turf mode since we don't know what parameters the ecu decides when switching is ok... probably stopped. The front diff is 4500rpm iirr, but the manual also says not to switch front diff on the fly. Stopped is safe for either diff imo.
Get a switch and wire it directly to 1 of the 2 wires coming from the diff plunger solenoid. Use key switched power. Ground the other wire to the diff solenoid.
Done

Yes I am very familiar with Trombetta products, there contactors are top notch.
But that type of solenoid is industrial application,not power sports or automotive.
And where would the 3v, with the needed amperage to pull in the plunger, come from? Certainty not the ecu or speedo cluster. Plus its only a 2 wire set up. No 3rd wire tap. Also the wire diagram posted above shows 12v to the relay feeding the solenoid, and an ecu ground, nothing else.The ecu ground probably lets the relay only pull in when the ecu determines its safe for the diff to unlock/lock, probably that means stopped.

Again we can put this all to rest with a simple reading of the sticker.
My bet is its 12v only.Thats what I can read on it. Everything after the 12v looks like maybe serial numbers to me. My old eyes can't see 3v any where, but with the angle its hard for me to read it.

Come on Dmax, post it up....

Maybe it's something in the solenoid also. The fact that 34ford couldn't get it to work with a simple 12V constant is why I keep blabbering. The relay schematic does look like it's a simple 12V switch, but there's something more to it than that.

How much was the solenoid? I may have to pick one up to tinker with. My landscaper would appreciate it if I had turf mode. :rofl3:
