    Since nobody apparently knew, putting this here for reference.

    The below photo shows the wiring for the driver side taillight. The white/black wire is ground and the larger yellow wire is the turn signal wire. On the passenger side, the turn signal wire is grey. These are the two wires you need to bridge with the resistor to fix hyperflashing.

    The next photos show where I mounted the resistors. They shouldn't come into contact with anything here. Basically I put them up as high as possible while still being able to get my drill in to mount them.

    I put spade connectors on the ends of each wire to the resistor and then added another length of wire to them in order to be able to have enough slack to lay the taillight on the tailgate without straining anything.

    I used posi taps and electrical tape to keep things tidy.

    Yes, This :thumbsup:

    ...and, if you are doing all 4 corners, you need 4 resistors.

    You mean the front too? Yes, in that case you would, but this is only the wiring for the rear.

    Yes, you need 4 if adding LEDs to the front also. Your wiring for the rear is spot on!

    I haven't bothered with the front yet. Not sure if I will.

    What wires would you splice into for the front? They are also numbered 1,2 & 3. #3 is the ground (b&w) on both driver/passenger. I am assuming #1 is the blinker/turn wire and #2 is the parking wire?

    Shit.. I tapped the resistor into the white/black wire and green wire. But it still fixed the hyper flash lol

    Thank you for this. Did my rear turn signals no problem.

    I didn’t have any screws that would hold the resistors to the inside panel so I used 3M tape.

    Props to the OP.

    This is perfect. I just had UPS deliver the led bulbs. How about front anyone?

    I didn't have to do anything special in front. Just swapped bulbs. But I did add extra resistors in the back since I did the tail as turn mod too.

    If you need them in front I think there's just two wires since they are turn only. I didn't actually look though.

    Yeah, I was annoyed i couldn't find any self tapping screws small enough.

    The newer LED 7440/7443/7444 ambers do not seem to need resistors. From what I've found, 7440 are intended for on/off only such as blinkers and taillights (not running lights).

    If the light has to function as both a running light and blinker/brake, they use 7443/7444 which have they hyper flashing issue.

    I used these for the front turn signals:

    These for the rear taillights:

    https://www.amazon.com/gp/product/B07559QVX5/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

    and these resistors:

    My passenger side randomly hyper flashes even with a 6Ohm resistor. Thought it was a bad resistor or crimped wire but no luck. It will flash normal even with lights on and as I make a turn it will begin to hyper flash. So weird. I want to do more like Tail light as Turn but getting this to work consistently is annoying.

    I had to add some 3Ohm in series to get mine to work with tail as turn.

    Here's the post:
