    Would pin 4 on the PQ12RF21 be the input from the turn signal?

    No. In this case pin #4 is not connected. The power cycling on the normal turn signal feed wire is fed into the Sharp regulator (PQ12RD21, PQ12RF21) and each time power goes off the circuit resets and starts over again.

    Do you need an adjustable rate turn signal flasher to leave power on long enough to get the speed of the sequence you want?

    Most people try to work within the blinking pattern they get from their OEM blinker. I customized my OEM blinker so that I could have the exact sequence timing I was after so it looks perfect.

    that's why the 5k pot is put in. you turn the dial to set the speed desired.

    I don't mean the speed of the sequential LED, I mean the amount of time the vehicle provides power to light the signal. Say your car turn signal applies power for 2 seconds. Does that mean you have 2 seconds for all the LED to go threw their entire sequence?

    I build the circuit on a bread board and it works...kind of. The led's don't stay lit. They just keep going over and over in a sequence. Anyone have any idea what I did wrong?


    Thank you for all the help guys, without it I couldn't even get close to this far!!!
