Let's install the "upfitter switches"

[THE YETI]

I'm just wondring, can I get a setup so I can install some fuses or a fuse on the battery of my LBZ (06' 2500HD) similar to the fuse for the plow with this kit? Im installing a winch on the 06 and some other things and this style set up would be clean ...

The dark coco color interior is called "Very Dark Atmosphere" Now look carefully at the part numbers as it depends on how your truck is outfitted with OR without a key type switch. I did my own taking my time and I can say you will have to disassemble the entire (or most of it) the center console. Do a search and a good article is on Diesel forums. I had to redo the entire writeup in MS Office as the photos were messed up. I again took my time. I utilized my own means and methods. 

 

Good Luck

Chuck

so what style switches are these  momentary or latch or both

[Robo9831]

So what type of switches doe this kit have. is there momentary and latching. or ar they all latching switches  i need momentary for air horn. two im thinkinmg about retrofitting the button panel to the upper roof console using the sunglasses compartment.

 

[THE YETI]

I believe they are all the "latch" type.

Not for sure what you mean, but these button click in and stay in with a light illuminated when pressed. You have to press them again to disengage.

Hello everyone. im new here. but i have been searching and browsing for answers. does anybody here know why this kit will not work on a 2017 gmc 2500hd. the only thing i can think of is cause of the gray plug that plugs into the factory harness. They probably didnt start putting that factory plug in till 2019 and up. if so  i can hard wire it in. i just need to know what wire is what  thank you

Man you all are so lucky that the newer trucks have this factory (custom) option.. I have a 2017 GMC Sierra 1500 SLT that I want to add switches for, but I don't think this will work for me. Am I correct in that?IMG_4690.HEIC

Hey Cali Crusin, were you able to figure it out on this kit to install it on your 2017. im in the same boat man. im sure someone has a write up wiring it up with the plug. (hardwire )

[TheElementalCashew]

You could probably get most of it working if you really wanted to. Like you said, the gray plug would be the most difficult because it is only on the newer trucks. That plug is the BCM controls, so I don't know that it is as easy as just tapping wires, but it could just be for backlighting, ignition position sensing, etc. 

 

Good luck if you decide to tackle it. It's difficult enough on trucks that were designed for the kit. Personally, I'd just find a different aftermarket kit and find a clean way to wire that up. 

[mobilelists]

This is really a great discussion on installing the upfitter switches.  I just got my 2022 3500 that was ordered with the kit as an option.  Much to my surprise I found the switch cluster was already installed in the knee bolster and now just the wiring remains.  After actually reading the UI Bulletin I see that the 2500/3500 have the knee bolster with the switch cluster installed during the build.

 

So the relay/fuse box and power cable remain to be installed.  The cables from the fuse box can be easily connected to the power cable and the 14-pin connector Aux Fuse Block.  But, I can't see the connector on the back of the switch cluster for the 16-pin switch bank connector.  How do I install that connector?  I find it hard to believe, but not impossible, that the switch cluster would be installed in the knee bolster at the factory, but then would have to be removed to install that one connector.  Can the switch cluster be pulled/pushed out to expose the connector or would that damage it?

 

Thanks for any help.

[THE YETI]

I'm  not 100% sure on what your exactly talking about.  BUT if you mean the connector that plugs in to the back of the switch in the knee bolster.  It's included in some bubble wrap and you install the provided wire to that connector after running through the firewall then plug er' in n go.  I installed this with ease in no time at all and I think of myself as electrically illiterate.  You don't have to remove rhe switch panel deal to install anything. Although I'm sure it more than likely is possible.

[mobilelists]

Do you remember if there was a socket on the back of the switch cluster that took one of the cables from the fuse box?

[TheElementalCashew]

Go all the way back to the first page of this thread and look at the pictures and instructions for opening up the dash. Once everything is unscrewed you can just pull the panel that holds the switches forwards to access the plug from the fuse box.

OK we are rounding the last corner and heading for the final stretch of this phase.

 

First, grab the fusebox, and hold it near where we'll be installing it:

 

First, the black plug you just put on the red wire from the first steps, plug that into the fusebox. I don't have a picture of this, but there's only one place it can go.

 

Next, take the grey plug from the fusebox harness, and plug it into the grey plug where you removed the blank/empty end:

 

Next, run the last unused black connector from the fusebox to the actual upfitter switches on the kickpanel:

 

At this point, you're switches are wired into the harness in your truck. 

 

One last step here - and this is where you may deviate from what I do. Because I knew I didn't want to take all this off again, and because I didn't have specific screws that would work AND because the screws that I took off the truck did work, I reused them. You may want to do something different.

 

In any case, match up the two screw holes in the fuse block with two empty holes on the support beam right behind the kickpanel, directly under the steering wheel. They're kind of hard to see, but I did manage to get a picture of me tightening down the screws.

 

 

So, once it's tightened down, double check that you've

1) plugged the grey plug from the harness to the grey plug where you removed the blank connector

2) plugged the black plug from the harness, through the supports, out the dash, and into the back of the upfitter switches

3) plugged the new black plug that you added the red wire into the fuse box.

 

It maybe is also a good idea to see where you left the four loose (electrical tape) wires. Whatever you wire to these switches is going to have to come all the way back to one of these four wires. (Sorry, this is one case where Ford got it better- their wires are all outside under the hood. Sorry, I don't like saying that either, but theirs is better.)

@mobilelists you can see in this post the plug that was used for the switches.

So it appears that the kick panel still has to be removed, or at least partially removed.  I will have to see if I can borrow a  scope to look up there and try to connect without doing that when I have some time.  The metal support brackets are blocking my field of view.

You don't have to fully remove it to access the back of the switch. I didn't fully remove mine, I just bent the plastic enough to install the fuse box and connect the switch. Pulling the panel back really isn't hard at all, removing it entirely would be difficult.
