you must have a running light wire hooked up with a blinker wire, that way it thinks that the blinkers are on constantly like running lights.
should have used a turn signal socket instead of drl socket. atleast that's how I did mine.
Why does everyone use resisters and hack splice shit into their wires, when you can just lift the pin on the bcm that controls the "light out" function? ComeonNow

I forget what pin it is, it's been a while since I've done mine.
But the module is under the dash on the driver side. You lift the pin that controls the "light out" function, which is what causes LEDs to hyper flash. The truck thinks there's a light out due to low current draw of the led. This you know.
There's a thread on GMFS I believe. And corny has done it a few times, maybe ask him real quick

I don't know how it works, but I seen it in Cornell's build thread.
Remove lower dash panel, rock that black box back and forth til you can pull it out.
Open the box with a screwdriver or something, I used the key to my truck
Clip pin #7, kinda a pain cause its so small.
Install back in truck and no more hyperflash. Stolen pics from Boo5ted.
