In our Oct. '04 issue, we showed you how to install Mustang Project's cool sequential LED taillights in a '65-'66 Mustang. This time we're switching gears by using a '69 instead of the earliest of Mustangs. Just like the first couple of years, the '67-'69s also have three-bar taillights, which makes these cars as receptive to this intriguing and easy-to-install upgrade.
For the most part, installing the LED modules in a '69 is much the same as with a '65-'66, but there are some differences, so the procedure takes a few extra steps and a little more time to complete. The main task is completely removing the taillight housing, which doesn't need to be done with the older cars because once the lens is removed on a '65-'66, the LED taillight-module simply plugs right in.
In any case, installing Mustang Project's kit is still easy on '67-'69s, and we were ready to go with cool Shelby/Thunderbird/Mercury Cougar-style sequential turn signals in about half an hour.
The sequential taillight setup...
The sequential taillight setup consists of just three components; a pair of LED modules and the flasher module that plugs in under the dash. The module replaces the stock flasher that makes the clicking sound when the turn signals are used. The sequential flasher doesn't make a clicking noise, so you have to check the dash indicators to see if a turn signal is on.
Unlike the earlier cars where...
Unlike the earlier cars where you only have to remove the frame, lens, and bulb, the '69 taillight housing has to be removed to install the LED module. Begin inside the trunk by unbolting the housing from the taillight panel.
Once the four nuts are removed...
Once the four nuts are removed and the taillight socket is unplugged from the housing, it can be removed from the car.
