I have a number of customers who have added
sequential systems to their 1964 T-Bird. I recommend using the
TS-400-64T system for ease of installation.
It works with the "Plasma" LED bulbs that are much brighter than the 1157 bulbs - a bonus safety feature. The reduced current will help your turn signal switch last much longer too. You only need to add two 18 ga wires from the front turn signal lights to the trunk. These signals allow the controller to distinguish between turn signal and brake light mode thus avoiding sequencing the brake lights.
The rear tail light turn signal/brake light socket feeds must be separated for sequential action. This can be done by cutting the original harness or installing a pair of new C5SB-13406-AR '65-66 T-Bird tail light bezel harnesses and C5SZ-14405-P2 pigtails to connect to the controller.
If you choose to use an original style 1965 T-Bird
sequential controller, four wires must be run to the trunk: brake switch (18ga) , brake power (12ga), Right front and Left front (16 ga, both controlled by the sequential box). Also, the 3-pin
flasher must be removed and the special current sensitive 1965-66 Thunderbird indicator relay (
C5SZ-13A366-CR) must be wired into the rear turn signal feed for the
sequential controller.
