Hey guys I got this idea from a 15 Tahoe there small leds under the dash. There the same color as the door handle lights and the light in the overhead. Gm lists them for like 20 each.

My question is on the Tahoe they must be wired to the interior /dash dimmer switch. There not bright they give a soft glow on the floor at night. How would I or where can I tap into that function. Other then running wires to the overhead shine down light.

Meaning the gray wire works when the switch is turned on? Or when a door is opened. On the Tahoe These are on whenever the dash lights/park lights are on. And you can dim them with the dash as well. Is the gray wire the same wire I’m talking about just wanna be sure thanks.

Also anyone interested in doing this the mounting locations where these go on the Tahoe. Are on the Silverado no modifications at all other then tapping into the power source.

If you want this LED to be tied to the ambient lighting that stays on and is controlled by the dimmer switch, it will not be the gray wire.

The gray wire is the interior dome Lamp circuit.

The wire you want is a yellow wire that is the “Ambient LED Dimming Circuit”. It is in the one of the connectors toward the right side of the BCM. I’ll get a pic of the tomorrow.

Thank you Phil once again you are the man I did see a few wires in the diagram but not exactly sure what wire as there were a few labeled dimming. Thanks again Phil. Also I ordered some of that wire from Remington.

Found it.

And actually - This circuit is also present in the Grey Connector (X7 BCM Connector - Far Left most Connector).

Same yellow wire, same circuit # 6817 (LED Backlight Dimming Control). The grey wire next to it is the outside mirror puddle lamp.

I’m actually happy about this too.. I want to have my door handles light up all the time at night and plan to diode mod it to the same circuit.

Yea that’s def gonna look really nice I wonder if you could have just tapped into the light on the inner door handle? But it’s prob easier to do it now without pulling the panels apart.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      I dont care what Lake says. Goodnight.

      Oil Consumption

      By Atlas · Posted

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
