electronic lock differential switch

[ShinHee Han]

Does anyone know the way of activating electronic lock differential after the front lock components were installed in my non-sasquatch outer banks?

If you're referring to OEM components you'll need the OEM hero switch (on the upper dash) and I presume the wiring harness from the hero switch to the FDU as well. Most likely will need to some forescan changes as well. There may be more specific threads out there, try a search here on the site or google.

If you are looking for any old way to turn them on, any switch rated for at least 10A will work fine. A relay would be ideal. It works like a light bulb - apply 12V : locked. Turn it off : unlocked

It does have a polarity requirement - there is a (+) and (-) side - just like an LED light, and it will break if you hook it up backwards

yeah i also equipped the OEM switch upon the dash but the engineer concerned about the connection between front differential lock and terrain mode.
ex. when the drive mode is changed to rock crawl, the ECU module automatically turn on the front lock differential.

thanks for your explanation but im willing to make my outer banks as the same as Wildtrak

You're trying to get the modes to control the front locker? I don't think any automatically turn on the front locker; it's demand only, you don't really use it except in small bursts. It impacts your steering. Also, the WildTrak doesn't have Rock Crawl mode by default, although it can always be turned on with FORScan.

As @Brian_B noted, you just need a switch run to actuate it, which with the Aux switches is easy if you have them. The dash buttons are computer controlled, so you'd have to get a new switch part and get into the computer controller and that's unlikely to end well, if work at all.

Goat modes shouldn't have any effect on the front diff lock operation...it simply needs to be manually disconnected via the hero switch, just need to be in 4-lo for it to engage.

Here’s an earlier thread that seems to have kinda died where they were trying to get the hero switches to work on a vehicle not originally equipped with them.
