Looks like a ripper now. I am working on installing a BMS midtravel.
So are you running race hubs up front and that is why you lost the wheel speed sensor? I haven’t looked at their long travel in a while to remember what the options were.
I was thinking on going with a fabricated housing down the road and was thinking about how I might be able to use the oem switch for the locker on another electric locker.
Anyways to your question, do you know what the requirements are to lock the locker? You could probably wire up a switch/relay and send a home run from the battery or from a distribution box if you have one.
I wonder if the oem switch still has power going to it with your abs missing? If it does, you could use the out front that switch to witch a relay.
