LED help please

Ok so here's the dilema.

I'm running 4-3157 bulbs with 63 leds in each one. 2 white for the front, 2 red for the rear. Also in the front corners are 2-194 5 LED bulbs.

I have bought the electronic flasher box to fix the "hyper flash" but that's not seeming to work. (Napa EP-27)

With the parking lights off:

Both blinkers work fine, but when you use a blinker it blinks all the dash lights. Same with hitting the brake pedal, lights up the dash, WITH THE LIGHTS OFF.

With the brake pedal on, no signals worked when clicked down or up (left and right).

When the hazard is hit, they both blink but with no blinker mod up front the corners blink with the blinkers.

With the Parking lights on:

Rear brake lights work, but no blinkers. Blinker stays solid on the dash but doesn't change outside. I HAVE NO TURN SIGNALS AT NIGHT!!!!!

Now I do have modded 06 tails to do the take turns flash with the top and bottom bulb. And as of right now (til the new LED 906's get here) I have incandescent bulbs down there still. Could those be causing anything?

I do know you can run a resistor in line for the wire for the blinker at each corner, but I don't know the resistor value for that or if it would even work? I tried shane's LED flasher and still, did nothing.

I need help asap guys! PLEASE!!! Jp7, Bob... Anyone!?!?!?!

Full LED situations have been casing wierd isses with the electrical.. I -think- the only positive way to fix anything related to it, is to sit down and do the math for the proper load-changing youll need to do to trick the vehicle into thinking its full incandesents.. even on that night right befor eyou showed up, we had a wierd issue with shane and myself using the LED's.. they werent flashign right and all kinds of wierd things were happening between switching them in and out.

^^Yea...but remember....yours are 3156's....single 'filament'...and we were using them as a 3157...dual filaments.



Tre....delete the 3rd bulb mod on the tails. See what that does. Shoot....swap back to incandescents in the front and LED in the rear to see what that does.

Turb'z will definately chime in here in a lil bit.

Wild guess, but did you wire it all up correctly? You mentioned adding some flasher box, do you know for a fact that isn't messed up? I would personally replace every thing with OEM equipment and then start going through everything to find out where the flaw is in this system. I'm guessing that using all LED's is confusing the crap out of the computer becuase it is drawing far less energy than it was designed to.
