<strong>Regardless, it does not appear that RLP pulses the motor. I am not sure what it does, but it sounds like it serves a role in blinking the LED and perhaps allowing the Diff Lock ECU to detect when the Diff is locked (however if the limit switch has been reached, I don't see why the Diff Lock ECU would care).</strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">I am with you on that one. I believe the diff lock detection switch is only used to light up the light on the dashboard and perhaps turn off the ABS. When I was running the motor while it was separated from the diff, the motor would turn both directions whether I had the diff lock detection switch open or closed. This tells me that the limit switches, NOT the detection switch, have sole control over the motor's operation.

Your second diagram (blue) looks fine to me, with the exception that I'd hook the LED to a constant +12v power source rather than behind the Control Switch. </strong></font><hr /></blockquote><font size="2" face="Verdana, Tahoma, Arial, Helv, Helvetica, Sans">Fair enough. I can merely tap the +12V wire before the dash switch rather than after (the way it is drawn above).

This method seems fail-proof, but I never would have guessed that RLP sends those crazy pulses!?! I just assumed that the only time current would be passing to the rear differential is when the locker is changing states. Obviously not the case. I will hook up the volt meter to all six wires (at the diff) and see if they are getting power at times other than when it is locking/unlocking.

This has been a great thread! Thanks guys!
