Hi Tim, we are trying to stay proactive and get back to everyone so let see if I can help you out. If you want to know where the chimes and signa chime end you can set up a Multimeter up to the white and white black on the harness's (signal Side) and turn the radio down and the turn signal you should see a spike in voltage (AC) when the signal pings.

 

If this is in the harness up to the processor or amp, it could be that it is tuned out by a low pass filter or may be disabled in the hmi. The loop harness is dumb it is simply a fancy tap that extends your connection point and saves you time and money. Hope this helps ! 

I actually contacted LLJ directly several months back and got no response but figured it out after also contacting WAMS, Kicker, and AudioControl. There was a change from the 19-20 to 2021+ ios radios (and maybe other variants). 21+ require a load generating device/resistor for the radio to see everything as normal and chimes to function. I contacted kicker after seeing they changed the GM factory sub add on part number. The change was the addition of an inline resistor to their harness. Hope this helps.

Awesome yes this is a solution on the new ethernet 6 radios. Glad that was figured out.  Thank you for the feedback

Did you ever find resolution to this issue?  I have a similar predicament; installed LLJ loopback harness with audio control amp ~8 months ago; everything worked great.  I just installed the WAMS radio upgrade and everything works, except now I have no turn signal/chimes sounds.  Everything else works.  I unplugged the loopback harness and reconnected factory plugs and I had turn signal sound again.  I also noticed that if I get in and just turn on the ACC and don't start the motor the hazards make sound, but as soon as I start the motor, silence.

I was able to fix the chime issues by installing these inline with the front dash speakers:

Another person on this forum was troubleshooting the same issue and we were PM'ing back and fourth. He was also able to resolve the chime issue with the part linked above.

      What did you do to your "other" car (aka musclecar) today

      Even tougher is the 5.0 / 302. That's what this one has.    https://postimg.cc/Z9XRrCSg   https://postimg.cc/4n3F3yzY   Just realized I had the airbox removed in the engine pic, lol.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.
