It gets the signal from the T harness. You unplug the grey harness from the audio control module and plug it into one side of the T harness. The other side of the T harness plugs back into the ACM. The long end of the harness routes back to the amp.

I cant speak for everyone else but I have been dealing with a loss of chimes altogether. Took my truck into the dealer earlier this week and they didn't know what the issue was. They contacted GM tech support which suggested they replace the radio. They replaced the radio today and still no chimes. Next they disconnected the subwoofer harness removing it from the mix and connected the original harness to the radio and the chimes started working again. I contacted Kicker and they told me that they have had several reports of this issue and are currently working with GM on fix. They took name info as well as my VIN and said they would contact me when they have a resolution. He asked if my truck was a diesel, which it is. He didn't specify but sounds like maybe it only affects the diesel trucks.

I believe that wire that gets spliced is a 12 volt turn on signal for the amp. If it were a single speaker tap it would require splicing 2 wires for positive and negative.

Took the truck in to the dealer. I installed the GM Kicker subwoofer kit part number 19417166. It's a plug and play harness but the tech traced the problem to subwoofer. When they unplugged the harness for the subwoofer and plugged the original harness back in the chimes returned. I explained to the that it's a GM part so not sure where to turn at this point. I want my subwoofer working but need my chimes working too.

Maybe you should reread my post instead of replying with a smart a$$ comment. The manual only addresses adjusting chime volume. If you read, or better yet comprehend my post I have no chimes at all. There is nothing in the manual about turning the chimes off altogether.

Did you ever find a solution to your no chime condition? I juts purchased a 2021 Silverado 2500 and I don't have the chimes either. No turn signal chime, no seatbelt chime, no headlights left on chime, no back up sensor chime and no chimes at start up either.

I just bought a 2021 Silverado 2500HD. When I'm backing and get close to objects I get a caution symbol that flashes up on the screen but no audible beeping. I looked in the manual and it says in the settings under collision/detection system the following may appear: Alert Type Forward Collision system Lane Change Alert Park Assist Rear camera park assist symbols Rear cross traffic alert. The manual goes on to say that alert type sets the alert from either beeps or safety alert seat. When I go into my menu under collision/detection system I dont have options for Alert Type or Forward Collision system but i have the other options lane change alert and so on. Am I to assume that because I don't have alert type in my settings menu I have no audible warning? Seems odd that it would have a rear backup detection system that shows visual warning symbols on the screen but no audible beeps. Even my 2019 work truck beeps when I get close to something while backing up. If I don't have the audible warning is there a way to add it?

GM has incorporated bass roll off into their audio systems for several years not. As the volume gets louder the bass decreases so as to protect the cheap OEM speakers. Since this kicker add on system gets its signal form the speaker output I can only assume that this subwoofer is prone to bass roll off as well. Has anyone noticed this and found a way to overcome it? At what volume level does the bass start to roll off?

Tried to read thru each page but got more and more confused. I have a 2015 Silverado 2500HD with the Duramax diesel. I have traction control, cargo lights and the exhaust brake so I would need switch cluster 23145163. I want to use one of the auxiliary switches to control a light bar. The light bar has a relay harness that has 2 wires that go to the battery and a longer 2 wire harness that goes into the cab that connects to the supplied toggle switch. Where do I connect these 2 wires that would go to the toggle switch in order to use the auxiliary switch?

I have the exact same noise coming from mine. Sounds like grinding gears. I've only had my 2015 Sierra a week and never noticed until the day after I had my lift kit installed. I had my lift installed at a shop out of town, about a 200 mile trip. Drove down in auto 4x4, no sound at all. It wasn't until on the way home about half way into the 200 mile trip did I notice it. First time I heard it was when letting out of the throttle then it would stop as I was coasting. As soon as I got back into the throttle I would hear it again and then it would stop but as soon as I let out the throttle it did it again for a short distance while coasting then would stop. Again as soon as I hit the throttle it did it again. I was beginning to think the shop had did something wrong until I read this post. I put my truck in 2wd and haven't heard it since. Once I got home I put the truck in 4wd just to confirm it was still engaging.
