something to keep in mind. almost all the trucks with leather have memory. If your truck does not have a communication wire for that memory module the seat will not move. the leather swap on my 22 rst ltd it was plug in play but previously i had a 22 custom ltd and it didn't have the necessary wiring under the driver seat. I had to run 2 positive wires for the passenger seat. one for lumbar one for recline and frame movement.

to get the info in the cluster you have to run two wires from the radio module to the cluster On cluster 19300632 is the terminated lead part number. pin 1 - pin 17 + on the radio connector 6 the small 12 pin connector. I can not find part numbers for individual wires but the entire connector part number is. 13529935 pin 3 + pin 4 -

This is my experience on my truck. The process may be different with your own vehicle. Some trucks are prewired completely some are half way wired some don't have any of the wiring. In my case my truck was half wired (from the overhead console down to the driver kick panel, but not populated in the driver side fuse box). My driver side fuse box did not have pins for either relays or the fuse. I can not speak on what the process would be like if you truck is completely prewired, but if none of the wiring is present this will get you really close. You can opt out of purchasing the over head console if you want to put a momentary switch somewhere in your truck.

If you have a 23+ custom even though it appears you have the old dash you have the new communication technology so you will need to use a 22.5 and up overhead console. Obviously you will need to get the glass installed. I suggest getting a professional to do it and price will vary. In my case the glass company removed the rear seat for install I asked them not to reinstall to make it easier to get all the wiring done. Charged me 250.My headliner harness already had wires running down from the over head console to behind the glove box, continuing on too the driver kick well area. If yours does not have them you will need to either purchase a headliner harness or populate them in your current harness or mount a momentary switch . These wires will be your relay trigger. Pin 5 on the overhead console connector is the open signal wire and pin 6 is the close signal wire. Under the passenger side of the dash close to the kick panel their is a large connector where the headliner meets the dash harness. pin 23 (close) and 52 (open) this is where I chose to cut the wires on the dash side of the harness and extended them to the rear cab wall. Run your wires as you see fit, I ran mine up alone the passenger side door opening frame under neath the carpet and plastic trim. I pulled a positive and off my amplifier wire and grounded to two of the studs on the cab wall. You can either run a wire directly from the battery or you can pull power from the passenger side fuse box. Your truck your choice just be smart and add a fuse. If your switch works backwards swap the trigger wires at the relay or the wires going to your motor.

What did you find out or get accomplished?

I have a 22 ltd I have got everything installed originally I wasn’t getting anything, tailgate would not release from the exterior button or the interior button. It wouldn’t even beep. After some digging. I found out the red and gray power wire was populated on the chassis harness but didn’t run from connector x140 to the left side dash fuse box for power. I got the power wire ran now my tailgate opens and the module beeps. but the lift function still isn’t working. I have not verified if I have gmlan again the wire is populated but I’m not sure it actually goes where it needs to. I would assume it does because I have blind spot monitoring and in a wiring diagram the rear end gate module and blind spot shows to share the same com wire. Can anyone chime in to help. Is it possible I have a bad motor? It was new but this gm parts we are talking about I’ve seen them fail out of the box.

I have attempted this upgrade. I may revisit it in a couple weeks. I’ve pieced some info together they maybe can point someone in the right direction. If you have a ior radio you have to have onstar for this to work. A new screen is required, ior and iOS/T radios are not the same. You will need an adapter harness of some sort. I used a speaker break out harness from metra. Some wires move between the two connectors. 2 or 3 wires have to be ran to the onstar module on the driver side of the dash. A new Ivds cable is required. Optional but I ran the wires to the cluster for audio info to display. That is as far as I got with the upgrade. I was able to get the radio to power on and display info in the cluster but was not able to get the screen to come on or the steering wheel controls to work. So I got audio info but couldn’t control the radio any.
