How to bench test front locker

[Godwin]

I've searched and haven't found anything that gives clear instruction on which wiring pins for 12v and ground to test the locking function of a front locker. The plug I want to use is on the locker wiring harness of the front axle. If it's like the rear locker, IIRC, only two pins are used and depending on which gets 12v and which is grounded determines the locker action. Correct?

Pins 2 (L-G) and 1 (L) are for the motor.

Pins 4 (L-B) and 3 (L-Y) are the limit grounds.

Pin 6 (W-B) needs to be grounded for either 3 and 4 to work.

I probably wouldn't run the motor without the limit grounds involved.

Either pin 3 or 4 should have continuity with ground (pin 6) at rest. My guess, according to the EWD, is pin 3 has continuity with pin 6. Check with ohm meter.

Use that pin as the ground for the motor and apply power to the other motor pin. Either the motor goes the distance and locks the locker, or the stops quickly due to loss of ground.

I see no difference between the way the front and rear locker actuators work.

This is according my EWD: 1996 LX450. Yours maybe different.

Correct. All 3 actuators work the same way and can be tested with a 9V battery.
Pins 2 and 3 run the motor, pins 4, 5, 6 are the limit switches.
All 3 use the same connector and have the same pinout.

To test the motor operation pins 2-3 with a 9V. One direction locks, reverse polarity unlocks. Very simple.
You're not going to hurt anything with a 9V unless you're a knucklehead.
