  1. Here’s a video I did that goes over the harness and install. Sent from my iPad using Tapatalk
  2. I make a harness that will allow you to have factory functionality of fog lamps. You’ll use a factory headlamp switch with the fog lamp button. The only difference from factory installed fog lamps is the indicator on the cluster won’t be active as it requires BCM programming. For those interested, please send me an email to [email protected] It helps me keep things organized so I don’t miss anything. I’ll need to very a couple things with your existing wiring.

  3. Looks like there is a module. #14 Sent from my iPad using Tapatalk
  4. It shouldn’t be too terrible a task for vehicles that already have the power fold 3rd row. In the default factory functionality, the seats won’t fold while the vehicle is out of park. That’s going to be controlled by the BCM or a separate module. I believe it will be a matter of tapping into the appropriate wiring, creating the harness, finding a location and mounting the switches. I would use the same type power fold switch that’s in the rear. Sent from my iPad using Tapatalk
  5. That’s an interesting idea. Would you use an existing button or add one? Sent from my iPad using Tapatalk
  6. I have a 2015 Yukon SLT. Here’s a pic of my adjustable pedals. Arrows are pointing to the motor and cable that adjusts the pedals. Would you post a pic of your pedals? I’m curious if adding the adjustable type will require replacing the whole bracket. Sent from my iPad using Tapatalk
  7. In short, yes, it’s doable. I believe the park position switch is still present even without adjustable pedals. See if the wire is at position 23 of the X5 connector and position 13 of the x7 connector at your BCM. The relays at the X51L fuse block are the printed circuit board (PCB) type. I’m aware of only one part number for that fuse block, so they should be there. While you’re checking for wires, look at the X51L - X1 connector, pos 15, 20, 28, 33. You’ll need to remove the connector cover to see the wires. On the X61A junction block, check the X5 (pos 25, 29) and X8 (pos 16, 18) connectors. My hope is that you have wires landed in all the spots except the X8 connector. Report back with pics if possible. Sent from my iPad using Tapatalk
  8. I’m looking over the wiring. Based on what I’m seeing, I don’t think BCM programming is needed for those without seat memory. There’s some wires I’m going to ask you to look for. I’ll post instructions later today. Sent from my iPad using Tapatalk
  9. Thanks for the pick. Here’s the switch you’ll need. There may be one without lane departure, but I haven’t found it. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F232648849366 Sent from my iPad using Tapatalk
  10. I’ll look into it. Can you send me a pick of the switches you have just to the left of the cluster? Sent from my iPad using Tapatalk

    I tried to send you a PM, but I can’t tell if it went through. Here’s what I sent. Sent from my iPad using Tapatalk

    That’s been my experience in the past as well with the aftermarket HID parts. I can build a harness for you. I just sent you a PM with instructions. One suggestion. The HID bulbs included from the factory are Osram 4300k D3S type. I swapped in the Osram 66340 CBI D3S bulbs and have been very happy. https://www.theretrofitsource.com/d3s-osram-xenarc-66340-cbi-54703.html Sent from my iPad using Tapatalk

    I have done this exact swap. The entire headlamp assemblies themselves are a direct swap. Unfortunately, on SLE & SLT Yukons the voltage that is sent to the halogen headlamp bulbs is pulse width modulated (PWM). It means the voltage is pulsed rapidly by the BCM. Here’s a video I did showing what that does to factory Denali HID headlamp assemblies. You can see how the PWM voltage causes the HID ballasts to rapidly turn on/off until they go into protect mode and shut down. I created a custom relay harness that connects between the headlamps and factory harness that solves this problem. The only evidence is an occasional notification via the OnStar diagnostic alert email that a bulb is out. There are no notifications/warning lights that come up on the cluster. It’s been working great for almost 2 years. I create and build various wiring harnesses for the 2015-2019 GM full-size suv platform. Sent from my iPad using Tapatalk
  14. Thanks for that info and pics. More pics of the large and small mirror connectors would be great. Sent from my iPad using Tapatalk
  15. Your thinking is correct. The running lamp and cargo light features won’t work as GM never offered tow mirrors on the K2XX platform SUVs. I make a set of harnesses that will enable those functions. Email me the brand & model tow mirrors you purchased along with some pics of the plugs and I can tell you what’s needed. cmattbuild1 AT gmail DOT com
