Ford Mustang 05-09 Sequential Turn Signal Harness

Good instructions, part fitted as described. The fitted harness is a little tight to the furthest away bulb socket, probably best to fit that bulb (#3) first and work back to #1. Fit the harness retention clip last! My old reverse bulb sockets on my car were extremely tight, had to use pliers to get the 1/4 turn. New ones went on well. I used the phone cable. Sequence is a little faster than I thought it would be but that’s more of a function of my flasher unit. Very straightforward job with great result.

Easy to put in and work perfectly. Watched a quick YouTube video on removal of lights and went to work. 30 minutes later was done. Since car was an ‘05 some of the clips hold trunk trim were brittle and broke. Just age related. Good product. Worth the investment.

These turn signal harnesses are awesome, They look, feel and fit like the originals and correct a design issue that Ford dropped the ball on when they originally designed the car. The instructions were great and the install went perfectly. I took some extra time during the install to clean behind the tail light assemblies and zip tie some wiring to prevent any issues. I highly recommend this product and seller who shipped super fast and the item arrived several days ahead of the scheduled delivery date.

Easy to install and work as described and safer when driving since they stand out when turning and driving

The directions made this light assembly easy to install. I love the sequential pattern. It provided a retro look to my ‘05 mustang

Bought these for my 2007 Mustang GT.Purchased Led's to go with them and then started seeing posts about hyperflash and how you need to splice in resistors to make them work right due to voltage or how the car would throw off a error message. Dam Dam Dammm...I am not about to start cutting into my wiring harness so I bought some standard 4057 bulbs to go with it.Anyway, went to install the harness and plugged in my Led's just to See...OMG, They Work Perfect. And No Error Messages Nor do I get the dreaded hyper flash.Not sure Why they work. Don't know if it's the Harness, The fact that the harness sequence keys of the cars flasher, the Led's I bought. They have No built in resistor on them, Or just being a 2007 mustang. Whatever it is They Work and I am flipping Thrilled...... Your Milage May Vary...IF you want Sequentials This is the harness to Buy.

I have a 05 mustang which didn't have the sequential turn signal. I wanted it so I found this on amazon. I had switched all my exterior lights in the car to LED to make it brighter at night because the lights that were in there were just terrible. I installed the kit and it didn't work so I called the number that it gave me and talked to the guy. He said he test them all before shipping them to his costumers which made me think I was doing something wrong or hooked it up wrong. Long story short LED don't work in the kit. Which is fine it works great I love it but would have preffered the LED in there. Just know if you plan on getting this don't use LED lightbulbs or it won't work.

Very impressive! Good instructions. Installation was pretty straight forward. Sequencing timing is "Spot On" I bought these as opposed to the others that are out there because of the phone chord that cancels the sequencing when the brake lights come on. Now all 3 brake lights come on each side instead of 2. Should've came this way from the factory. Thank you for a very high quality product! Definitely install all new bulbs as recommended, 6 each 4057 and 2 each 921. I didn't use LEDs because I prefer the original factory look.
