A picture sometimes works better. Below is a modified diagram showing the diodes.
With the two diodes placed as in the diagram, and the DPDT switch in the off position (switch is open), while in 4 low, the dashboard switch that controls the lockers can now cycle through rear only locked or all locked.
With the original wiring and the DPDT switch in the off position in 4 low, both lockers would be locked even in the rear only setting on the dash.
When the DPDT switch is in the on position, both front and rear lockers will be set to lock with my modification regardless of the dashboard setting just as in your diagram.
Unless your saying that in the unmodified circuit in 4 low that this circuit and the dash lights saying all locked or rear locked is a bogus setting? From what I can tell that is why there are two separate outputs otherwise they could have just combined both lockers onto one output and it would be all locked or none locked.

So, are you saying putting the diodes in so that the lockers can operate normally when the switch is in the off position would be better?
Also, when you said there is an lsd and a locker what is an lsd?
What is the manual wrong about, the speed at which it de-activates?
When you said that "a ground on either pin 41 or pin 42 will lock the right axle" did you mean right axle as in right side of the car or the correct axle?
In case you are wondering, I can tell what the electronics does but that doesn't mean that I understand what the hardware does that it is connected to. My expertise is in the electronics not the Jeep . In the past, I've been called in to do some consulting work to solve an electronics problem on machines that I have no clue about operating. That is why they have machine operators.
I enjoy this site because of the sharing that goes on.
I have a number of certifications in electronics including a teaching certificate. I think it is my first passion. I'm also certified to teach IT.

|lee indy||okay the manual is incorrect. you have an lsd and a locker in the rear. the rear is not always locked. a ground on either pin 41 or pin 42 will lock the right axle. lockers are fun in snow and sand. but 4 lo is a pain in the arse when you need momentum.|

|jk'n||The speed that it will disengage is 10mph or 18kph. I don't know why that feature would need to be disabled above 10mph since when moving that fast, it would be unlikely for one of the wheels to be spinning while the other is grabbing for any distance.|

|jk'n||OK, I went out and checked it. I also read about it in the owner's manual. As you had said, it is available in 4 low. The rear stay on all the time. The front can be cycled on and off. This means that pin 41 and 42 may not be connected across as the diagram shows and still have this function normal in the switch off mode unless the diodes are used.|

|lee indy||last i knew you could only engage the lockers in 4lo and it engages both. and if you exceed 18mph it will unlock them. this mod defeats all that and lets you lock up in all tcase positions and it turns off your esp. all in one switch.|

|jk'n||I'm going to have to check this and get back. As I recall when in either 4 high or low, pressing the lock button cycles through all locked, rear locked or neither locked but my memory is fuzzy on it right now. Since this is my first 4wd I'm still trying to memorize situation vs. feature.|

|lee indy||but you cant operate them independently in the factory configuration....? right?|
|06-09-2009 04:16 PM|
|jk'n||With the DPDT switch in the on position, both front and back will be locked (pin 41 and 42 grounded through the switch). However, with the DPDT switch in the off position, normal operation will not be possible because the two pins,41 and 42 will be tied together. Whenever one output goes low the other will go low with it and will result in not being able to command the front and back independently. Inserting the two diodes as per my previous post will allow for normal operation while the DPDT switch is off.|

|lee indy||and with this mod you can still engage the lockers in 4lo and is still factory looking|
|06-09-2009 03:30 PM|
youve confused me and its not the sparky speak im an avionics tech. are you saying that with my toggle in the down position the tie link between the engage signal wont be able to lock them individually? you might be confused with the link to the locker mod i posted. that one gives you seperate control of the front and the rear. this wright up doesnt. they are either both locked or unlocked. if you want independant control you can ad another single pull single throw toggle for the front locker and engageing the rear locker will still defeat the ESP. the idea behind that is you dont want abs and anti skid when your wheels are locked. i guess you could just use the dash switch but it has on semi on and off. thats a pain. ive heard the dealer will disengage it for you if youd like.
any one have a diaghram for the ESP

|jk'n||OK, I'll take a poke here. By combining the outputs on pins 41 and 42 without any isolation between would mean that when the lockers are commanded independently, both would lock. Suggest putting two switching diodes in with the anodes facing pins 41 and 42 and then tie the two cathodes together and run to the switch. This way, the pins 41 and 42 can still be commanded independently by the chip output when the lock switch is in the off position.|
