I'm in high and I haven't done the pin 7 mod or added the cdl switch - yet. It's on the way with a few other parts and an FSM/EWD. It's worked great until I high centered in the sand.
I blew out the connectors and cleaned them yesterday. I've been banging on the actuator and doing all the shifting and other monkey business as per usual when this happens. The only good thing is my lockers will engage/disengage in high w/out the pin7 or cdl.
I think it's something simple as I didn't hurt anything when I high centered. I wonder if there's a switch or link that goes from the High Low shifter that may not be working right.
