[Turbotoys]

Here are the wiring schematics for the Stereo and Amp. If anyone wants any other wiring let me know and I will post em up.

Radio

Amp - it is located behind the jack bracket in the rear of the vehicle.

Nice! Thanks...

Fog lights please??

Made this a sticky so that it is easier to find when someone needs it. Good job.

Very interesting. Multiple subwoofers in the same room (vehicle) perform in some very interesting ways when given the same signal. This is a common technique used to clean up modal response problems. The remaining question is which one, or both, are being used for ANC.

 

[Rush]

We definitely know T3/X1 is being used. Don't know about the others.

There is only 1 Subwoofer - if you look at the diagram above there is only 1 positive and a negative for subwoofer. There must be a misprint or they are using a postive signal from the one side and a negative from the other side to sum a mono channel to the subwoofer.

Look at the following sheets - no mention of a second subwoofer.

Thanks. Rick. Looking at the fog schematic, does that more or less mean that the fog lights are controlled by the BCM? And wiring after the fact would be more complicated and require programming?

 

[Turbotoys]

Im pretty sure everything is controlled by the BCM

Are you trying to add factory fog lamps?

Yes. On the older trucks you didn't need a BCM flash to get the capability but I'm hearing that the newer gen requires it.

Here is another break down I found just giving speaker wire colors.

Can anyone tell me which plug on the radio and which wires on that plug would be used to add a audio/video input. I know they sell a harness for this and it's like $400 for it so I know it can be done. I have the non rse with nav radio. I'm an electrician so I'm familiar with doing stuff like this. I just looked over the different plugs and wiring and I'm not 100% sure which wires are for the audio/video inputs. If anyone could help I would appreciate it. Thanks

Does anyone know where the amp is located on the 2015 LS Tahoe? or is it just a part of the head unit?

Black Grill and other parts

Nice! Thanks...

what did you do to get your grill from chrome to black? Just sets things off!

Nice! Thanks...

What did you go to get the black grill vs. the chrome?

BCM Wiring

QUOTE= If anyone wants any other wiring let me know and I will post em up.

Do you have a schematic of the BCM for a 2015 Tahoe LT?

I would like to see if I can come up with a mod to transfer the DRL function to the LED's instead of headlights.

Thanks

Turbotoys, can you post the wiring for the wiring of the rear seats? Installing a power 3rd row seat in a non power 2015 Tahoe.

Thanks,
Andrew

Radio schematic's rocked.

X1, X2, X3. X3 only has the low speed data, no canceling mic's. this is 2015 Lt with 9 speaker Bose.

X4 has all MOST wiring. Brown connector.

What about wiring diagram for the OEM Rear Entertainment screens. I have a 2015 Yukon Denali XL and am considering either replacing the screens with Ipads or wiring an HDMI input somehow - the OEM only accepts older IOS versions to connect and doesn't accept video from IOS.

View media item 25561Does anyone know where this grommet ends inside the passenger cabin?

I need to run a set of wires thru the firewall down the left side of the vehicle towards the grill.

I was looking at the connection box next to the pedals in which it appears the writing harness comes into the cabin from the engine but it doesn't seem to line up with the grommet pictured.

It's usually higher up in the dash. Like not far under the dash pad.
