  1. Seat Memory Retrofit (RPO - A45) by pgamboa So I gave everyone a sneak peak of my radio that showed the “Comfort and Convenience” options. This option is an option when you have the A45 - Seat Memory Package, typically found on LTZ, High County, SLT, and Denali Trims. Since owning my truck (2016 Silverado LT, 1500 CCSB), I started down the path of adding Seat Memory because I thought this was upgrade path in order to add DL3 Mirrors (power fold, turn signal, puddle light, etc.) I originally only wanted DL3 Mirrors but it seemed (at the time) that I could or would need to add Seat Memory since all the circuits for DL3 Mirrors and their harnesses were built for Seat Memory. When I realized that adding Seat Memory was never going to happen and couldn’t be done, I always wanted to know why. The MAIN reason why it has been said it couldn’t be done, wasn’t because that it couldn’t, but because of all the hardware, wiring, and programming requirements needed in order to achieve it. There is a HUGE parts list, a TON of wiring, then the programming. I’m here to share my retrofit details with all of you! Let’s start with my truck first. 2016 Silverado 1500 LT, CCSB, Gas, 5.3L, 2WD. Came with Factory Heated Leather Seats, Power Adjust Driver Seat, Power Adjust Pedals, Rear Park Assist Sensors, Rear Sliding Window, DL8 Mirrors. I came across an opportunity to buy a complete interior that came from a higher trim truck (mainly for the heated/cooled seats is what I wanted) and took this opportunity to give this another shot, considering that I would have a majority of the hardware. Retrofit Requirements: First and foremost - Programming. There is a K40 - Seat Memory Module that lives under the Driver’s Seat. This needs to be programmed to your truck. Programming done by WAMS - www.whiteautoandmedia.com. @GTPprix Thanks for this! The K40 Seat Memory Module was sent off to get programmed to work with my truck/my VIN. Hardware - DL3 Mirrors, DL3 Door Harnesses, DL3 Door Panel Harnesses, DL3 Power Fold Switch (different than the non-Seat Memory Power Fold Switch), DL3 Passenger Window Switch (DL3 Passenger Window Switch has two inputs as opposed to one), Heated/Cooled Seats, K40 Seat Memory Module, Pedal Adjust Memory Motor (still need to source one). Wiring - There is a TON of wiring needed. There are about 10-12 circuits that need to be added to the driver side seat connector X310 (cabin side). These circuits go forward and land in various places (X51L Fuse Panel, X61A Junction Box, Pedal Adjust Motor, Passenger Seat, both Door Jambs (cabin side), Passenger Side Kick Panel). You will also need to access both door jamb (cabin side connectors) to remove circuits that will no longer be used in favor of new seat memory circuits. So, as you can see, you will have to have the ability to overcome this as it can be a bit overwhelming. You will also need to ability to comprehend the schematics differences between Seat Memory versus non Seat Memory. There are several circuit redirects and circuits that get abandoned in favor of new circuits to live in those slots, etc. So…as you can see, this is why it always been understood as “it can’t be done”. I have everything working EXCEPT for the pedal adjust - memory recall. I can manually adjust the pedals using the adjust button on the I/P. The pedal motor is different in Seat Memory versus Non Seat Memory, so I will be exploring that soon. It seems that I am missing a pedal position sensor. This is fully functional now Here is a list of what I gained and what is working: Key Fob Mirror Fold In/Out Reverse Mirror Tilt Mirror Memory Pedal Memory Seat Memory Set Switch 1 & 2, Easy Exit Heated/Cooled Seats on both seats Power Adjust Passenger Seat Power Adjust Driver Seat Driver Seat - Haptic Feedback (when in Reverse) What doesn’t work Pedal Adjust Memory Recall - This is the last piece of this upgrade and is a work in progress. I am exploring the requirements for this. Pedal Adjust Memory Recall works now after installing the Pedal Adjust Position Sensor. $15 on eBay for that. I couldn’t drive my truck for 3 days since the driver seat was moved ALL the way forward when it was removed from the donor truck. This was done to gain access to the rear bolts needed to remove the seat. I was NOT able to get the power adjust on the driver seat to work until day 3 of this project, therefore, making the truck not driveable. I inadvertently had to make a “Seat Memory Bypass, Power Adjust Harness” to be able to move my seats in the meantime. This custom harness bypasses the Seat Memory Module and provides power to the adjust controls. Depending on the need for this, I may make/sell this harness for those without seat memory that want to install these heated/cooled seats, and be able to adjust the driver side. The Driver Seat adjust controls go THROUGH the Seat Memory Module. So until you can get entire system to work, you won’t be able to adjust the driver seat. If you currently have Factory Heated Seats, adding cooled seats is rather simple and is plug and play (no programming required). If you DO NOT have Factory Heat, I don’t know how much more work is needed to gain that. Most likely, you’ll need programming for the K29 Seat Heating Control Module and/or BCM. Since I have Factory Heat, the K29 Seat Heater Module was already present under my factory seat, so to gain cooling for the Driver Side, I only had to land one wire for the Vent Motor from the passenger side over to the driver side. For the most part, the passenger seat was Plug and Play. I was able to quickly gain power adjust on that side since its controls do not interface with the MSM Memory Seat Module). However, you WILL get an airbag warning error because the seat position sensors are all handled by the MSM. Without a fully functional MSM, you’ll have to add the physical Seat Position Sensor to get this error to go away. There is really NO easy way to integrate this. No Plug and Play harnesses that will make this all work. So please don’t ask me about one - LOL. You really need to have an understanding of how to add missing circuits and circuit redirects. I had to redirect circuits in 4 places. I did make 2-3 mistakes in this project. I forgot to land missing circuits (totally missing them) and I landed circuits incorrectly - blowing the pedal adjust fuse. So…you have to be fully prepared if you decide to tackle this project. Here are some photos to share. I also took some video clips of the entire process and will try to put a video together. Enjoy! Dash Swap was done only because I had the seats already out, so might as well swap out my vinyl dash for the leather that came with the interior I bought. Since I had to remove seats and carpet to gain access to the cab side seat connectors, might as well Sound Deaden. Lol. New Comfort and Convenience options! Cab Side - Passenger Seat Connector (X320) Cab Side - Driver Seat Connector (X310) - With my harness loom of new circuits added. The dreaded X61A- Junction Box An impromptu harness I had to make to adjust my driver seat without the MSM working. The impromptu bypass harness. Can’t drive like this. Seat now adjusted to optimal driving position! LOl
