'm getting mixed information on subject and have just ran across your site and am hoping the two of you can shed light on my problem.

I have an 06 Ford Mustang Stage 2 Roush edition and am in the process of swapping out the incandescent bulbs with LED's. I've taken some time to enlighten myself on the subject and know I need to swap the factory Relay with an electronic one due to the low load LED's put on the system but the problem I have is locating the Hazard/Turn Signal Relay that is suppose to be under the driver side dash. I can't find it even after ripping the dash completely apart. It has Roush Gauges and that is where I hear the clicking sound coming from but the Flasher isn't in there either. Some say that the flash is controlled by computer while others say that the Flasher is there under the dash. Ford sells two types of flashers for the car so I'm assuming there is one. Some even say there is one for the turn signals and a separate one for the Hazards.

Any Light you can shed on this for me would be greatly appreciated.

Thanks In Advance for the Info

Hello,

The turn signal flasher is interrogated into the smart junction box.

The flasher function for this vehicle is provided by the Smart Junction Box (SJB).

Here is a guide to help and the blinker wiring diagrams so you can see how the system works below and how to replace the SJB.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

My right side turn signals/ brake light do not work although the left work fine. I checked all the fuses and bulbs, and they all seemed to be fine. I also have had a problem with it blowing a fuel pump fuse under the hood from time to time. I was wondering what could be causing it, and if the same problem could somehow cause both of these problems? Something such as a bad ground somewhere maybe?

A test light will let you know if you have a bad ground problem.

Should be about 15 bucks at most part stores.
