Jake you make some very good points. The switch must be able to handle 20 amps. There are 20 amp toggle switches at Schucks and other auto places. Second, good point you made was the motor burn out if the switch is left on too long. That's where the key is in having a relay. The guys at Slee Offroad know their stuff. :)

Man, Jake I am tempted to have you throw me together a parts list and pay you. :pat:

FWIW I was able to get the ECU setup to work with a slightly modified version of the first wiring diagram in this thread. I just followed the wiring diagram and didn't complicate things by really trying to understand it. :) It was pretty much plug and play. Here's the modified diagram I used:
http://www.geocities.com/transalper/...ker_wiring.jpg Instead of usng the resistor and new bulb, I just hooked the indicator circuit to the existing in-dash light (like Lars did for his ARB). My best hunch is if you are trying to us the ECU as a stand alone unit, it wont work. I think it needs input from all the sensors. Sort of a "Fail Safe" system. If the ECU does not receive a signal from a sensor it will not lock the locker. Maybe Bruce will chime in on this. |

The sensor input is not needed. I tested the ECU/locker on the bench before installing the 3rd and it worked fine. So you just ignored the yellow/blue from the lock detection switch? |
Probably another dumb question, but what is the best way to test whether or not the e-locker is working with this set-up? The reason I ask is because I have the front seat out and crap everywhere. So, if the best way to test it is to go out and engage 4WD, then I need to know.
My method of testing has been to have my wife push the RR diff lock button while I was at the rear diff listening for the e-locker motor to make a sound. I heard nothing. |
<96 Runner>, see if this helps out, I had this posted elsewhere;

If so, check the green/yellow wire pin #4; e-locker switch off = no power, on = power also you'll hear a clicking noise from the box, which is a solenoid engaging. If you hear this noise check the light green wire pin #3 for power; this is power going to the e-locker motor to engage. If so check the light green/red wire pin #2 to see if it is grounded. If so, your ECU is ok, now you need to see if actual power(switch on) is getting to the e-locker at the axle. Check the green wire at both connectors, frame and locker motor to see if you got power, if not then the problem is somewhere in the wiring harness. If power is going to the motor then you'll need to remove the assembly and check it out.
If the switch in the E-locker that tells the ECU which relay to activate, doesn't close it's connection properly this will prevent the system from working. Pin #9 should be grounded if the switch is working properly, if it's not, you can try grounding this lead to see if it activates relay 1 in the ECU, this sometime will jump start the system and fix the problem. I can't see how your having problems if you took out all the parts from the donor rig and it was worknig before hand. Do the checks above and let me know, I'll try and help walk you through... |
Thanks Bruce, I will test all that tomorrow night and report back.
The donor rig's locker was working, I tested it. However, instead of stealing the 4WD/ABS ECU controller from that rig, I had to buy one from Jim (which should be no problem). Like I mentioned previously, I know power is going to and through the 10A and 20A 12+ respectively. It is reaching the locker ECU, but for some reason it is not leaving the ECU to the e-locker motor. Everything is grounded. I will report back tomorrow night. |

OK guys, I just tested everything and I am pretty sure the ECU is no good.
Pin #5 power? YES Pin #4 power, switch on? YES I hear no sound of a solenoid in the ECU engaging. I tried to ground Pin #9 to "jump start" relay 1 in the ECU, and nothing happened. I also noticed that the ECU has JB Weld on it, which concerns me. I wonder if the owner of the ECU before Jim did something to it? I have spoken with Jim on PM, so I am not concerned about returning it because we will work that out between us. Any other ideas before I contact Jim? |
Someone mentioned earlier that the gears had to be moving to allow the locking fork to move into position.... is there a sensor or switch that is tripping this? What position was the locker in when you installed it (locked or unlocked, i would assume unlocked)?
It does seem like the ecu might be bad. Building your own bank of relays and a couple resistors wouldn't be hard. |
I agree Steve. And the donor rig was unlocked and in awesome condition. No worries there. My concern is not hearing the sound Bruce said I would hear when the ECU successfully recieved and relayed the incoming power. I am not getting that, and JB Weld scares me. :dunno:
Looks like I might have to build my own. Dang, I guess I have to go camping this weekend with old school 4WD (2WD really). |
Bummer. I could work on compiling a wiring diagram for you if no one has one ready yet. Let me know.
|
Mighty kind of you! I will let you know. Maybe there is another ECU out there somewhere...:dunno:
|
Here's a wiring diagram... this guy made his own controller. It's about 2/3 of the way down the page.

wish I had some more ideas or schematics to show you. the e-locker ecu is one of those mysteries that at least one person tried to find out about (hint JB Weld).
|
<96 Runner>, too bad you don't live near me, I have a brand new ECU in a box. I picked it up, just in case I fried mine during dissassembly....
Weird that there is JB weld on it, they come apart easily without any problems. I'd say there was a problem with it if the relay didn't click. BTW, Why didn't you get the one out of the donor rig? |

I would love to find an ECU so I can verify it is the problem. Maybe someone around here will have one I can try. One good thing is that I can still drive the rig and I have 4WD. Therefore I can take my time and get this done right. I still don't know what my best option is at this point. I guess trying another ECU would be smart... |
Intresting on the ABS circuit, I'll have to trace it to see how to bypass it, but mostly to install a switch to turn off ABS while wheelin.
