Aux Switches

Quite possible. I really haven't kept up. I would think the term smart might be way overkill, though.

True. Smart only in the sense that the alternator can vary the output voltage based on input from external controls.

does anyone know the part number for the crimp terminals that are on the 10 inch wires they give us in the wiring pack that we are to plug into the light grey and dark grey connectors next to the aux power panel that is rearward of the drivers side battery?

looks like there are 2 of them, a 1/4 inch variety as well as an 1/8th inch. they are male crimp connectors.

Yazaki 7114-4142-02 are the correct terminals that handle cross section wire of 3.0-4.0 mm2, which is about 12awg. Yazaki 7114-4143-02 will handle 10awg.

Only the larger are used in the Aux connectors.

I believe the smaller are for the upfitter PTO plug connections.

Sorry, don't have the PN.

And like @brutal said ^^, those two connectors accept only the larger male terminals.

you guys are awesome, thanks

here is a supplier who seems to not think these are made of gold....
connector: https://www.questcomp.com/part/4/71...m_medium=industry-cpc&utm_campaign=partsearch
seal: Yazaki 7158-3016-80 i found the seals, but havent been able to find a source for them..

Update and maybe some guidance? Dealer installed the aux module in my truck, they could not get it to work. With the information from this thread here is what I found.
My truck does have the aux pdc
My truck does not have any of the relays or fuses in the pdc and it does not have the grey plugs to accept aux wiring not does it have the second set of connectors in the pdc. I ordered the new “aux wiring kit” from dodge part number 68398184ac it’s 30 bucks.... I also ordered the two plugs for the side of the pdc that accept the wiring tat would go to aux items. Does anyone know if this kit Ram is selling will have all the wiring I need to get my aux switch’s to work? Was this kit available when this thread was started? I see many mentions of ram not having a “kit” is this the kit they would have referred to? It literally is sold as an auxiliary wiring kit...

No, that’s not everything needed to to get the switches to work. All you ordered was the bag of wiring that would come with trucks equipped with the switches to wire up accessories. It’s the wiring that plugs into the gray connectors on the side of the aux PDC. You still need to finish wiring up your existing aux PDC for the relays and fuses.

Ok ty for your reply.
Another question.... am I going to have to add the wires from the switch’s to the aux pdc? It appears it has that side of the wiring in the pdc as it does have one side wired already. I am assuming the one side would be factory wiring from module to aux pdc.
Next do they sell the wiring you are talking about that I need to add to the pdc?
Would it be advisable to just find a wrecked truck that has this and buy the ore wired pdc?
Is the kit you guys on this thread are selling the wiring kit I would need to wire the pdc?

Yes you will need to run wires to the Aux switch from the Aux PDC. The wires you run will have to be from the coil output side of your relays and even though (I've been told and as mentioned in this thread) it's far easier to run the wires all the way to the Aux switch then what it is to try and connect them to the XY125A connector under the dash. You'll need one wire per switch. Personally I wouldn't bother trying to get anything from a wrecked truck as it's only wires, crimps, fuses and relays that you'll need from this point.
I've attached a couple of pics of the underside (with and without the bottom cover) of the Aux PDC. As you can see there is a busbar that runs through the centre and has the terminals already mounted into the fuse holder locations. Which means that the wiring you need to install is from the other side of the fuse, this is visible in the picture of the wires and you can the three fat wires at the top of the image coming out of the fuse location and going to their respective relays. I used this location to run power to both the main power into the relay as well as to the power side of the coil for the same relay. Then all you need to do is run the power from the outside of the relay to whatever you want to run and the wires from the otherside of the coil to the Aux Switch.



The kit that has been mentioned in this thread does include everything you need to wire it all up.
When checking to see if the Aux switches are recognised by the car you need to check your instrument cluster menu, the options should be visible under "commercial menu" and the default pin should be 0000. If you don't have commercial menu visible then the dealer can do that for you or you can go down the path of getting AFLAOBDII etc..

Hope this helps and sorry I don't have any pictures of what the underside of my AUX PDC looked like once I'd wired everything in.

Just a word about overload: The maximum stock power capacity of the truck is 440A - running dual 220A alternators on the diesel, or 360A if you're running dual 180A alts on the gasser. Any load higher than that will drain from the battery and drag the alternator voltage from 14V down to the battery level at 12V or lower. A theoretical 600A load would pull at least 160A continuous from the battery. (All assuming you're trying to run that kind of load while the engine running. )

I don't know what kind of protection is built into the voltage regulators Ram uses.

Just for clarification and future reference, the Hemi dual alternator package adds a 160A to the existing 220A, for a total of 380A.

Good catch. At my age, I've come to hate the tiny fonts on all their configuration screens. I went back and looked, and the 380 still looks like 360 to me.

Further clarification: the existing stock alternator is the 160A. (Options are to replace with a 220, add a 220, or do both.)

You’re definitely right as to what it’s actually doing, but the Ram site words it the other way around (as if the 220A is the default).

They really like to make stuff confusing.

A second alternator with 160 amps, along with the 220-amp alternator provides a maximum 380 amps with the 6.4L HEMI® V8 engine.

as for the other terminals in the Aux PDC, I was able to modify a standard yellow female connector to correctly locate into the slot.. took some time to modify and I even took a little video if anyone is interested... I'll have to figure out how to share that as it's a massive file size. basically what I did was lever up the middle section at the back enough to allow my diagonal cutters to cut the middle section, once that was cut through I bent up each side and trimmed to the correct length and then bent them back down. This modified female connector can be used in the input and output of the relay (from fuse and going to the item to be powered) total of 12 to wire all 6 relays.

Has anyone been able to figure out what the part numbers are for the relay terminals in the AUX PDC? I saw that Atty found some for the fuses and was able to modify some off the shelf ones to work for the relays, but Id like to get the right ones for the relays.

From reading through everything it sounds like BighornHDRam had figured it out and sold some to paulvi. I have tried contacting them to purchase but havent gotten any response.

The Google has led me to this site:

Custom Electronics for Ram Vehicles. Auxiliary button kits.

www.4thgenramelectronics.com

They specifically offer packages up to the 2018 model year. Seems to me there isn't any reason this wouldn't work for the 2019. I've also sent an email to the Upfitter tech authority people looking for clarification. I'll post any replies.

This is a hella interesting thread !
Been poking through aux switches and I’ve stumbled across some part number confusion. Perhaps someone can help a brother out ? 2019 ram 2500 bighorn 6.4 gas ... i have the toggle switches for traction control and tow/haul ... would like to add the 6 bank aux switch but can’t find the 6 aux with just those two. Any help would be greatly appreciated !

I got my switches installed. Now where to tap into the vehicle harness to access where the wires on the plug terminate.
My truck is a ‘19 Power Wagon, no PDC.

Will I have to re-pin a portion of the plug going into the new switch panel?

 

[BigSwede]

This is what I used and may work for others. Female connector is 1456989-3, female receptacle is 1393366-1, male connector is 6-1419167-1, male pin is 1438299-4. All parts are TE Connectivity.

Did you have to re-pin the connector coming out of the back of the switch panel? If so, which pins should be replaced?

 

[BigSwede]

I activated the switches today using AlphaOBD. I notice aux1 and aux2 can be activated with the ignition off, 4-6 require the ignition to be on. Is this the same for everyone? 2019 Power Wagon
