and u have nothing plugged in on the end of that harness??

Well, another person in a different group says he got a Reese 20142 adapter that makes it work.... trying to find one that's not in back order to try....

Yep... I bet you're right!!

yep... tried that and still no luck....

No sir.... didn't help...

Ya, I tried to just plugging in an adapter with no trailer and that didn't do it.... it's go to have something hooked to it some how...

Currently the outside mirror cameras only come on when the turn signal is on AND I'm towing my boat.... Has anyone found a way to keep them activated with the turn signals without towing anything???

Is this still for sale? LMK thanks!!

I have a 2021 Denali w/6.2 that has a truck built date of 02/21.... have 13k miles on it... I haven't noticed any issues yet, should I get the Pulsar sooner rather than later? thanks!!

Yep..... had mine for a few months now... love it!!!

Just got my 1N4001 diodes from Amazon and got one plugged in. Awesome! It works!! I was kinda hoping JUST the LED mirror lights would come on but the cargo light switch illuminates when I put the truck in reverse and the bed cargo lights and the reverse light comes on in the 3 brake/reverse light combo on the back of the cab come on too, but I'm good with that!! It's nice to not have to hit the switch when u want extra reverse lights. So this mod works on the 2019 2500HD's as well. thanks fellas!!

So are you having to leave that switch ON on the dash for the bed lights & mirror lights for the mod to work? Cuz my lights come on when it's park too and that switch is on...

Ok thanks for the clarification... Here's a pic of mine, they look the same...LOL But I'd hate to smoke something by stickin a diode in pin that don't belong......
