DIY Hyper flash Bypass Installation by KAMIL D.
If you installed LED in your car you need to put in this bypass because the lower draw of power by LED will cause your lights to by blinking like one of the bulbs burned down.
I don’t know how but this harness will fix that issue.
This will tell you how to install it :
Tools needed:
Small flat fad screwdriver
T-10X4 star screwdriver
1. Remove the Fog lamp/Trunk release switch plate by gently pulling away from the dashboard, then unplug the electrical connector. Once unplugged you will notice a screw behind it, remove this screw.
2. Remove the two screws securing the knee pad from under the dashboard.
3 Remove the IATS (interior air temperature sensor) cover plate then unplug the electrical connector. Once unplugged you will notice a screw behind it, remove this screw. (Skip this step if your vehicle is not equipped with the IATS)
4 Remove the dashboard knee pad from the steering column by gently pulling it away.
5. Locate and unplug the harness under the dash that is the original factory flasher harness, the harness should be directly below the Ignition key switch
6 Plug the Hyperflash bypass Harness inline/between the same harness connectors that you just unplugged in step 5 once plugged in. Once installed,test the operation of the new bypass flasher harness prior to reassembly!
That’s it your done

I bought a hyperflash bypass last year with hopes it will fix my turn signal issue that sometimes the turn signals work and sometimes they dont.
Ill be doing this modification this morning. Yesterday the turn signals worked each time I used them. Its hit or miss.

Very nice write up ! 
The reason the harness is needed is not because of the power draw though.
Its because when a normal bulb is blown the normal amount of resistance the car sees in the circuit goes to an open circuit (no resistance) . The car believes that a bulb is blown, and blinks the bulbs twice as fast. LED's have no resistance (just like a blown bulb). The harness fools the car into believing that there is resistance in the circuit thus making the blinkers blink at normal speed.

GOT IT DONE!!!!!! Thanks those are great instructions! Works great too!
Only problem is the two metal clips fell off and can't get them back on. What do I need to do to hold them on...... having a lot of trouble seeing under there to lock them back in.
