Hi guys,

I have installed a front locker from an fzj 80 Sahara into my gxl. This weekend I finally got around to trying to wire it in using a diagram I found on YouTube. Unfortunately this diagram did not match the wires which I had to work with. Mostly blue with stripes. I had bought spdt relays which were supposed to control limit switches in the locker. I know very little about auto electrics so I was very quickly stumped

Has anybody installed a factory locker by making a custom harness that they could share with me. As long as the locker will engage and disengage and not be continuously powered while not changing states I’ll be happy. I’m just really disappointed that diagram I had did not work.

thanks in advance
 
Here are a couple threads that have wiring diagrams and logic sequence for the factory system:


You will want to include the position switch logic into your locker wiring I would think.. I'm sure there's a way to do this but it may be easiest to find a diff lock ECU and include that in your system.

Here's the part of the manual for the front locker - "L" is for "Light Blue" so "LR" is blue with red stripe, etc.

This is why I went cable operated.

Yeah there are a couple slick cable installations using the factory locker mechanism on here somewhere, would be easier probably.
 
Awesome thanks for the help guys. See the thing is I found a good video and diagram online, I bought all the gear and went to install only to find different colours, think the diagram was for the rear. I’ll show the diagram I have. I just want to know how to do this same wiring diagram on the front

Thank you,
After having looked at that wiring diagram , the one I have posted below is now making sense to me at last, once I account for the different wire colours. The only thing which doesn’t make sense to me is the switch, I know very little about auto electrics so it may be obvious to most. Do you happen to know how that switch works ( in my last post on the thread ). It looks like there’s 12v going to the switch and it just switches which terminal it goes to, is that just what any normal switch does or is that a special switch. Thanks for your help
 
That's exactly what the switch and is exactly what a normal switch does. As shown in the diagram it is closed on the upper wire, which sends current through the lower right hand relay and to the "locked" limit switch. The relay closes, which allows current to flow to the actuator motor, which operates until the "locked" limit switch is reached and the relay circuit is opened, at which point the relay will also open and stop current flowing to the actuator motor.

When the dash switch is in the other position, closed on the lower wire, it sends voltage through the lower left hand relay to the "unlocked" limit switch. The relay closes, which sends current to the actuator motor in the reverse direction from above. The motor operates until the "unlocked" limit switch is reached and the relay circuit is opened. The relay opens and stops the current flowing to the actuator motor.

If you post up what relays and dash switch you plan on using we could help you wire it up from point to point.

Brilliant explanation I actually get that, thank you. I’ll definitely take you up on the offer of the wiring help and will attach photos of the relay and switch. Also I have 15 amp rated wires and a 10 amp fuse, will that be sufficient as it’s not going long distances?

Here is how I would suggest wiring up the relays, if you want to follow that diagram.

I am not sure your switch will work for this though. First of all, it looks like an AC rated switch instead of a DC rated switch. It also looks like your switch is an on-off switch, and what you really need is a rocker switch that sends power either to one place or the other. I'm guessing the wiring of yours is similar to this:

There is probably a way to make your switch work, it would just need to be wired differently than shown in the diagram above.

Perfect that makes things so easy, I’ve just gone and bought a switch with on/off/on positions so that will work perfectly. I’ve got a 10 amp fuse and 15 amp rated wire, think that will do the job?

will be a fun and rewarding job for the weekend
