Where are they. Pics?

I am trying to install a locker switch to my new D44 that replaced my D30 on my X. It did not come equipped with any lockers, but will now if I can ever figure out the wiring. My switch does NOT have a light.

I know there are write-ups already but the pics do not work and my simple mind needs pics.

Thank you all.

 

Well I'm not sure how it is going to help you but here is a pic:



They are in the back left corner, near the battery, circled in yellow in the above pic. Front is front, rear is rear.

Since your Jeep didn't originally have a locker you probably don't have a factory switch or relay... I don't know what you have but I am guessing you just want to run a 12v source through a fuse, through a switch to the locker, something like this:

+12v |----------~20A fuse-----------/switch-------------*locker

Hope that helps.

 

Confused, did you get the dana 44 with the elocker and are putting it in your X?
That's what it sounds like. If so, there are no locker relays. They are only in the Rubicon's. I have the dana 44 sitting in my driveway waiting for the install, I already wired it up to make sure the locker worked. If you want some help you may PM me.
But here is what I'm going to do. I bought the wiring harness from Quadratec for the rubicon, I wanted the actual plugs---it was a little more expensive. I cut off the plugs and I am going to wire the the plug for the locker to a relay--it doesn't matter where it goes, then to a switch. I'm going to wire the sensor to an LED and install it in the dash somewhere. The locker is a simple 12v connection. I'm ditching all the other garbage that cam with the wiring harness. Jeep made it way too complicated when they wired up their elocker. This way, I flip a switch and the locker is under my control not the stupid computer.

 

Thank you for the input and the pic. Ok. I do not have the relays for certain and yes - I am installing a D44 in an X model.

I have heard that I need a relay and cannot wire it straight in...also to not run it through power, because the locker works off of a negative source, not a positive.

I'm very confused.

I need this done by tomorrow. I leave for a business trip and when I return I am going to Hot Springs for fun.

 

A relay is required if the item (in this case the locker) draws a significant amount of current. A simple relay circuit:



Negative source? You got +12 and GND to work with so your only choice is to have the relay "switch" the +12 (like in the pic) or "switch" the GND (locker would be between the fuse and the relay).

Hope that helps.

 

Awesome. Thank you. I'll go get a relay. Thaks you all.

 

The locker doesn't run off of a negative source, the stock locker switch uses a negative sense to sense the switching on and off. I'ts really confusing but just related to the computer.

Here is how to wire your new locker.
The upper socket activates the locker. It needs 12 volts off of the battery. The driver's side pin is positve and the passenger side is negative from what I have gathered on the web. Wire the positve to the load terminal on the relay, the negative to the neg on the bat or a good ground. Wire the battery to the input on the relay and then wire the feed from your switch to the relay activiting pole. Ground the relay to the negative pole and attach a positive source to the other pole of your switch.

This is how I am going to wire mine, and Like I said I tested it already and seemed to work well. If it explodes your locker dont blame me, just trying to help.

 

On the relay make sure it is rated for at least 20A DC (you want the fuse to "die" first). A SPST (single pole, single throw) relay is all you need but others (SPDT, DPST, DPDT, etc.) will work they will just have extra connections that you won't use...

 

One more (hopefully) dumb question...

From what I gather, a relay is essentally a 30A max fused link. If I have an inline fuse installed at 2A, what exactly is the point of the relay? It seems redundant.

I feel dumb as a box of rocks.

 

A relay is not a fuse. It is basically an electrically controlled switch consisting of a coil and a switch. When a (small) current is applied to the coil (via the tiny switch inside your jeep) the switch in the relay is magnetically closed and can "switch" a MUCH bigger current to a device.

Basically, it lets you "turn on" things that require a large current (winches, fog lights, etc.) by applying a small current. Otherwise you would need a huge switch - one that could handle large amps - inside your Jeep instead of the tiny toggle switch you normally use...
