WT trim with Color DIC, Steering Wheel Controls, IO5 Stereo retrofit.

Do you have to change cluster just to have the radio control buttons, I have the wt truck Upgraded the radio to the 8" screen etc from mvi, I wouldn't mind just have the radio buttons and voice command on my wheel

Yes.

I assure you, it is worth the money to upgrade the cluster if you are wanting the steering wheel controls.

now I don't want the heated wheel, how much wiring am I looking at lol and if you could message me the parts I need lmao looks like I'm gonna go for it

First post. You just don't need the new clock spring. All the rest applies. I think there is a link to the terminals on page two of this topic.

Well after some work and some digging and some wiring I have finally completed the retrofit of my RCSB Blackout (Which was the WT trim with the small radio) to have the IO5 stereo, Color DIC Gauge Cluster and Heated Steering wheel with all the controls working, both the DIC and the stereo controls work. I would guess that total I have about $2000 tied up in all of this so it can get costly and it isn't for the feint of heart, you will be cutting into factory wires. This will only work if you have the IO4 option code, if you have the IO3 stereo you are probably out of luck.

Gauge cluster programming was provided by Chris over at WAMS, I highly suggest going to Chris for all your custom module programming needs. He is a busy guy so if you have questions on this swap you will want to post them here as Chris won't be able to help you out with anything other than providing the custom programming for the cluster. You can request prices from his site at: http://www.whiteautoandmedia.com/

All of the information needed to do this retrofit can been dug up from the upfitters electrical manual available at: https://www.gmupfitt...builder-manuals

If you plan on attempting this familiarize yourself with the information I post and this manual, it will save you some head aches.

Basically all you are doing is tying back the steering wheel controls to the gauge cluster on the LIN Bus (one wire, that doesn't exist if you don't have controls) and then adding the gauge cluster to the MOST bus via the stereo. This is easily done at the radio module behind the HMI (The top box, but you know this if you have upgraded to IO5 or IO6) just with the grey 8 pin connector which actually is where it shows the gauge cluster being in relation between the amplifier and the radio. You will want to put the gauge cluster in series on the most bus on wires 3 and 4 from the far right connector on the radio module. So basically you will cut these wires and where they were going in to the radio now they will go into the gauge cluster on pins 1 and 2 and the return to the radio from pins 17 and 18 on the gauge cluster, all this can be found in the upfitter manaul. Then you will want to grab the MOST enable signal from wire 7 on the connector and bring it back to the gauge cluster also, you can tap off of it.

If you have any questions feel free to post them here and I will try to stop in every so often and answer. PM's will go unanswered as I don't want to type the same info out 20 times so just post it here so we can have one post covering this. I will also try and post some diagrams and more pictures next week along with a link to the pins that plug in to the blank spots on the connector of the gauge cluster to add the above circuits.

But yes, this can be done.

Thanks,

Kyle

Hello, I'm a noob at this and attempting to glean enough to do the wiring mod you describe here. I already did the I06 upgrade and received the new upgraded programmed cluster from WAMS. I went through the upfitters manual you mentioned (long, geez), however, you already uploaded all the appropriate pages in your post. I'm pretty sure I get all the wiring instructions you've provided, but am fuzzy on what I need to get specifically to do this job.

Questions:

Do I need to purchase "pins" to go into "pin 1 & 2" and "pin 17 & 18" for do they already exist in the factory connector? If they are already factory installed, it's just a matter of removing them, crimping them on a new wire, then running them back to their new connection point, correct? Are there special tools required for this?

Is it an option to purchase an aftermarket harness and cannabalize what I need since it will have the wires and pins already or is there an easier/better way?

Sorry for all the questions, I've never done anything like this before.

Thanks in advance for your help!

You have to buy the pins, and it would be way easier to buy them and a crimper than to try and cannibalize an existing harness. I would suggest buying a crimper for the size pins involved but you could probably get away with manually crimping them with a pair of pliers or something, I used to do things like that back in the day but you are better off buying a crimper.

You mentioned sizes for these pins, do you know what size/type they are? After looking briefly online, it appears there are many. Thanks!

If you look at each drawing of the connectors on the first page of the thread, if a part # is listed under "Service Terminal", you can typically find them that way. If one is not listed, perform a google search for the connector description. Most results will return Mouser for the source.

So:

928999-5 and SAIT-A03T-M064 are the terminals. Also, the description for the clock spring looks close to the Radio connector. Order extras if you've never crimped these terminals before.

Page two I posted links for the pins and crimpers on amazon.

Wow, thanks for all the pictures and links to order, super helpful...Thanks Kyle and Phil!

Sure thing, if you have any issues just post on here or IM me and I will try to help you out but I think all of it is covered in one form or another on this topic.

I own a 2015 Silverado LS and recently followed the instructions for swapping the basic DIC out with the full color DIC and adding steering controls. The instructions were flawless and very easy to follow. After having a new cluster programmed by WAM (White Auto and Media) I was able to install the new cluster with minimal wiring in about 3 hours. The hardest part was removing the air bag (once removed it becomes clear how it detaches which is not obvious while its still in tact). Kudos to Darth_Vader and WAM automotive for the detailed info and programming. I was a little hesitant to mess with wiring but the direction given is so clear and accurate I went for it and am glad I did. Thanks guys.........
