Locker Mod>>>>>TACOSUPREME

[fabjunkie]

Ok, I have been fighting this way too long. I've got everything hooked up the way it's supposed to be. I used the RadioShack relay everyone says to use.

1. The switch works and moves the relay accordingly.
2. I have power to both terminals from the Violet wire.
3. The Grn/Blk wire has power when the locker is "off".
4. The Pink wire has power when the locker is "on".
5. Lt. Grn has power when the locker is "off".
6. Lt. Blue has power when the locker is "on".
7. I did not tap the ground wire in the harness. I used a bolt on the dash and it proves good.

All of this was checked with a trouble light.

Problem is the locker will NOT turn on. No indicator light, not even blinking, nothing. I have wrapped my head in, out, and around the wiring diagram and I can not figure it out. I used spades at the relay (obviously) and also at the harness. Everything is hooked to the truck side of the wiring like it should be. 4wd & 4lo both work.

Back to the garage.

is the locker computer good? How about a short in the actual electric motor?

[fabjunkie]

Well the ECU shouldn't be an issue as this bypasses it.

Messing with it some more, here is the update.

When the switch is "on". (power coming from the lt. green through the actuator to the lt. blue)
1. The lt. blue & pink now only light the trouble light up dimly.
2. No power to the grn/blk wire. (as it should be)
3. Lt. green and both violets are bright on the trouble light.

When the switch is "off". (power coming from the lt. blue through the actuator to the lt. grn)
1. Lt. blue, lt. green, grn/blk, and both violets all are bright.
2. No power to the pink wire. (as it should be)

Everything is wired correctly. I used the correct pink wire (the lighter one). I'm thinking maybe I fried the relay, hence the dim light on pink with the switch on. But there is a dim light on the lt. blue wire also. This would lead me to believe that there is something wrong with the actuator.

Going the other way once the polarity is reversed by turning the switch off, the light is bright on the lt. grn wire (as well as the lt. blue, which is now recieving power), which would not happen if there were a problem with the actuator. The light is also bright on the grn/blk wire indicating the relay is good on that bank. Fuck this is really starting to piss me off. As usual, a 30 minute job turns into a trainwreck. I've searched through all the threads on here, TS and TN and I haven't seen anyone else with this issue. Where did I go wrong?

[mojavegold]

All I can think of is, did you use a non latching relay? A standard automotive latching relay won't work with this application. Mine works a-ok. Also, the poles on some relays are labeled differently, so you have to double check that you are using the correct terminals on the relay.

[tacosupreme]

The first time I tried it I had the same problem. I was using a relay designed for use as a trigger, go to radio shack and get the right one and you will be good to go. If there is no radio shack in your area, you can order from their website.

EDIT: I just woke up and didn't read what you wrote. Uhhh fuck I don't know but the relay isn't latching. Did you drop it maybe? Test that thing on a bench with a small load and see if it works right.

[fabjunkie]

Yeah I don't know. Maybe I fried it plugging and unplugging shit last night. Either that or it was bad from the start. The contacts move as they should, but maybe the internals are screwed.

I'm just going to take it all apart and start over with a new relay. I'll let you know what happens.

[fabjunkie]

Got a new relay. Thought maybe my jumpers between the relay and the harness were the culprit. Took those out and hooked the relay directly to the harness. Same as before.

When the switch is "on". (power coming from the lt. green through the actuator to the lt. blue)
1. The lt. blue & pink now only light the trouble light up dimly.
2. No power to the grn/blk wire. (as it should be)
3. Lt. green and both violets are bright on the trouble light.

When the switch is "off". (power coming from the lt. blue through the actuator to the lt. grn)
1. Lt. blue, lt. green, grn/blk, and both violets all are bright.
2. No power to the pink wire. (as it should be)

I have the wires hooked up to the same terminals that I have seen posted many times on all the forums for part #275-218 from RadioShack.

Lt. blue>6
Lt. green>5
Pink>4
Violet>2&3
grn/blk>1

The switch controls the relay just fine. Still only getting a dim bulb on the test light on lt. blue & pink when the switch is on. I guess I'm going to hook it back stock to see if it works that way.

[tacosupreme]

Weird man. The violet wire still has 12V right? You are hooked into the right side of the wires? The ECU side of the wires should be dangling. Check your connections. Maybe something is loose.

[fabjunkie]

Yes, I am hooked to the harness side, not the ECU. Hooked it up stock and it works. Only thing I can think of is I have the wrong pink wire as there are two, a dark one and a light one. I am using the light one, which I believe is the correct one.

I'm going to try it again and see what happens. If nothing else, I guess it will be stock with a few extra inches of wire. Thank god for quick connectors or I wouldn't have any wire left under there.

edit: Maybe I'm using the wrong poles on the relay. I'm hooking them up as I listed earlier, the same as I've seen on many threads.

mojavegold, are you using the 275-218 from radioshack?

[fabjunkie]

Ok, I feel like a complete moron. Everything was correct the whole time, I just didn't know it.

Somewhere on another thread here (that I re-read today), a guy (don't remember who it was, sorry) posted that his light did not blink anymore, that it was either on or off (Logan, you were part of this conversation and stated that yours still blinks using a switch rather than a relay). After hooking the relay back up and driving back and forth in the driveway, turning the wheels left to right, still nothing. I came to a stop, hit the button again and the light came on. Checked and sure enough it's locked.

I don't know if it's because of the relay or what, but the light does not blink anymore locking or unlocking, it is either on or off as was stated by this other guy. But everything works as it should in 2hi, 4hi, and 4lo, including the ABS light coming on (I don't have VSC).

Moral of the story for those who are going to do this. Once you have everything hooked up, don't count on the blinking light. Get the truck moving and turning side to side to give it a chance to lock before you conclude that it is not working.

Now on to the 2lo mod!!

[mojavegold]

yeah, my light doesn't blink since I did the mod. Sometimes the obvious hurts...

[tacosupreme]

Oh well, at least you know the mod inside out now, and maybe next time this comes up you can chime in because I have a bad case of CRS (can't remember shit) lol

[makana]

I was just wondering guys if there was a write up possibly with pics on how to do the e locker mod to turn in on and off and not just under 5mph. Thanks Makana

[tacosupreme]

Yeah, the locker mod is made for just that. You can turn it on doing 100 mph if you want after the mod, just be sure you are going in a straight line. If you engage the locker in a corner on dry pavement you will watch your tailgate pass you right before you eat it. It's fun to use on wet roads just screwing around, but be careful with it. Here's the mod for the umpteenth time you lazy nonsearching noob.

Derogatory yet not quite offensive. This place is getting soft!

[tacosupreme]

well, you know... don't want to offend anyone's delicate sensibilities.

[45LongColt]

I am a noobie here, only had my Taco for 5 months now. Now I may be all wrong here but wouldn't it be a good idea to have "some" sort of light that the locker is on? Wonder if the kids hit the button or moma hits it inadvertantly?

You can just wire it up with a lighted switch. If you really want that.

[tacosupreme]

my light still works as normal. The lock light is fed from the locker indicator switch in the rear diff through the blue wire with the white stripe into the 4wd ecu, through the buzzer in there, up to the dash light. The only time you need to "add" a light is if you are swapping an e-locker rear into a non-trd truck.

[redhottaco]

Hey Tacosupreme, I would personally like to thank you. You have been so helpfull and kind with this mod and others. You always seem to come to the rescue when people like myself screw the pooch on this mod, generously giving your time and knowledge to help people trouble shoot their problems. Your write-up is excellent, and so is your effort in making this forum the best source of info on the web. And lets not forget the many others who also give so much of their time and effort to help educate stupid fucks like me, THANK YOU!

[tacosupreme]

thanks I guess, but I mostly stoled my ideas from others so I don't get all the credit. Most of it goes to Dick Foster, too bad the crotchety old bastard left us, I learned a lot of shit from that guy.

[redhottaco]

x2 on Dick, guess he knows everything now and has no reason to come back and tear people a new one. Too bad, there are alot of those old guys (old being a relative term) who don't come around anymore.

your not going to know this mod inside and out until you burn up your actuator because you leave the switch in the "on" position. FYI, once its locked, or unlocked, (and you have a DPDT relay) make sure you switch it back to "off" or you will burn up your actuator. trust me.

[tacosupreme]

There is a limit switch built into the locker so that doesn't happen. If you are parked and flip the switch and the splines aren't lined up, maybe it would burn out if you left it long enough, but for normal or modded operation it's safe.

[brinner]

not if its left in the ON-UNLOCK position without a cutoff when its done dis-engaging, it'll just keep trying to pull the pin even further out (with nowhere to go)

[tacosupreme]

something must be jacked with your wiring dude. There is no possible way that could happen. Take a test probe to your relay. When you flip it to locked the green/black wire gets juice until the locker engages and throws the limit switch, and then it goes dead. No power to anything, open circuit. Then flip it to unlock and the pink wire gets juice until it unlocks, then it goes dead, open circuit. Unless it gets hung up midway between lock and unlock, there is only power applied briefly therefore no way to burn up an actuator. What you just described won't work, if you flip it to unlock after lock it will "unlock". Or were you referring to the On-None-On switch? I'm not calling you out or anything, just trying to understand exactly how it could happen unless a) the wiring is jacked, or b) there is a mechanical fault in the locker (or operator) and the locker is not engaging.

[fabjunkie]

x2

The only thing the mod does is bypass the "safety" part of the stock setup that only allows engagement in 4LO. Other than that, it's the same as stock.

[hemiram]

if you don't cut the red/blk wire going from the switch to the 4x4 ecu and just tap into it to control the relay, then the ecu still thinks things are normal when trying to engage the locker and initiates the blinking light and abs bypass just like normal. Worked that way on my 07 trd

[tacosupreme]

what? who said anything about cutting that wire? and btw if the light is blinking that means the locker is not engaged, it stays lit when locked. if its blinkin' its thinkin'

It says in the step by step instructions to cut the Red/Black(Locker Switch) wire(3rd bullet from the bottom)...I am about to do the mod and would like to know if the Red/Black wire should be cut or if it should be tapped.
