Review on Mustang 05 09 Sequential Signal Harness by Doug Bunkers

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.
