Mustang 05 09 Sequential Signal Harness Review

Delivery was fantastic! The wiring harness completely replaces the old wiring harness, which was a good thing because at 89,000 miles on the stock wiring harness, it suffered badly from overheating. Fastening the seat belt takes a few minutes after you reach the seat belt, which can be an issue on a Mustang. The sequential flash is a little faster than the original but still great.

Arrived BEFORE the promised date which was great. This setup is very simple and straightforward. No hidden problems. The guide was great. I also googled the installation and trust me it's as easy as it claims. Just looks great. Worked on the first try. A bit pricey but really basic. (ps: I changed ALL the bulbs when installing. Good idea)

Took less than 30 minutes. The wiring harness fits my '09 Mustang GT exactly, everything on it including the rubber bushings and brackets is exactly the same as the Ford OEM. I like the consistency as the tail light now flashes 1-2-3 turn signals and an emergency flash. Inexpensive, well made and looks just like the OEM.

I installed this on my 2006 Mustang Convertible a few days ago. Installation went smoothly and took about 45 minutes. The instructions recommend replacing all lightbulbs during installation and I agree. I didn't and had to take one side apart to replace the bulb after putting everything back together. The product fits perfectly and is very nice to look at. Great upgrade for your Mustang.

These turn signal harnesses are great. The instructions were great and the installation went really well. During installation I spent extra time cleaning the taillight assembly and disconnecting the wiring to avoid problems. I highly recommend this product and the seller who shipped very quickly and the product arrived a few days before the scheduled delivery date.

Very impressive! Good guide. Installation was pretty easy. Sequence Sync - "Spot On". I bought these unlike the others out there because of the phone chord that breaks the sequence when the brake lights come on. Now there are 3 brake lights on each side and not 2. It should have been like this from the factory. Thank you for a very high quality product! Be sure to install all new bulbs as recommended on 64057 and 2921. I didn't use LEDs because I prefer the original factory look.

This was exactly what I was looking for in a serial kit. This is a direct replacement for the factory seat belt, and you can replace the factory seat belt at any time without cutting or modifying the factory seat belt. There is a wire (telephone wire) that you need to run from side to side to the wiring harness, it connects to the new wiring harness and my install was complete in about 10 minutes. It has all the correct harness clips and brackets. It looks like Ford came out with this product…

A touch of retro modern! The box arrived with 2 wire harnesses neatly tucked inside, with some instructions. BYOB (bring your own lightbulbs). This kit is less expensive than others I've looked at, uses factory bulbs and a taillight housing, and was replaced in less than 30 minutes. Do yourself a favor and use your old lightbulbs for now. DO NOT reassemble until you have tested the new suspension. If the bulbs are burned out, great, you only work a few minutes. If everything works with the old…

Bought these for my 2007 Mustang GT. Bought LEDs to go with it, and then started seeing messages about Hyperblitz and how you need to connect resistors to make them work properly due to voltage, or how the machine throws an error message. dam dam. I'm not going to cut into my wiring harness so I bought some standard 4057 bulbs to go with it. Anyway, I went to install the harness and wire up my LEDs just to see. OMG they work great. And no error messages. I don't understand the terrible…
