![]() ![]() Also #'s 3,4and 5 are in an insulated 'bag' wrapped in tape and held in by 2 bolts.Ī process of elimination is the best way to find the problem with the system, unless you know right where to check, start from the beginning, it's faster. Please note the names of the two different relays, and their location, don't let yourself get confused. ?ĕ) stop light relay also mounted with sequencer and turn relay ?Ĕ) flasher or sequencer unit mounted with turn signal relay ?ē) turn signal relay under the package tray in the trunk ?Ē) turn signal indicator relay mounted to the column support The basic parts of the sequential system are By unplugging the relay and using a jumper wire from the key hot to the green output wire, the system can be tested and parts can be ordered all at once. Another example is where a stop light relay is bad. An example would be where a brake light switch is bad, a jumper wire can be used to connect the two switch wires so the rest of the system can be tested. Jumper wires are used to either go around a bad part for testing, or bridging a connector that has to be unplugged for access. I like using a test light instead of a digital volt meter because they actually draw a little current, where the meter doesn't. ![]() All the wiring for the rear of the car starts under the console and continues under the rear seat. Finding a break in a wire can be tough, but should be done instead of just going around it with a new wire, the old one may still cause a short. Incorrect wire numbers or colors are not uncommon, the most correct I've found are from Jim Osborn.Īlso most schematics don't show the stop light relay, they show the wire leaving the stop switch and go directly into the turn signal relay. One problem that pops up from time to time is inaccurate info printed in the schematics that are reproduced and sold by parts vendors. I'm not sure how robust the Dodge turn signals switches are but this is a failure point in the Fords with 6 tail lights.This guide along with a 12 volt test light and a few jumper wires should get you to the bottom of most problems with the 65/66 sequential turn signal and brake light system. Note: It is highly recommended to convert the rear lamps to LEDs because of the high current that is drawn by incandescent 1157 bulbs. Orange/blue, orange/white, and orange/red are RH. The rear tail light connections are shown in the schematic: green/orange, green/red, green/black are LH, Note: They must not connect to the turn signal switch directly.ħ. The white/blue and green/white wires from the 6-pin relay connector feed the R & L front turn signal lights. The R & L front light wires from your turn signal switch connect to the 8-pin relay connector, violet and white.Ħ. Both R & L rear signal feeds from your turn signal switch connect to the orange/green wire on the motor-driven sequencer.ĥ. The stop lamp relay output, 14 ga green, feeds the 14 ga green/white wire on the 6-pin relay connector.Ĥ. The stop lamp relay 14 ga red wire needs +12V. The output of the stop lamp switch feeds the 18 ga green/white on the stop lamp relay.Ģ. If you review the schematic, you will find:ġ. It is solely used to drive the motor around to the start position after the turn signal lever is returned to the neutral position. The T- Bird sequencer has an additional 2-pin connector with brown, brown/white wires. You have the late '66 T-Bird system with the 4-pin flat stop lamp relay. I just have a mess right now on the table of un taped wiring and miss matched plug ends. So, what will do is run forwards with the wiring to the turn signal switch and stop light switch. It's in the tail end of my 1967 Dodge Coronet 500. Okay, now, here's the kicker, don't be unit isn't in a 1966 T Bird. ![]() I have the schematics and have figured out the numbers on the wires and the color codes. What plugs into what? What plugs into the three units bolted to the rubber plate. What I need is a definitive photo of what the entire tail light harness is supposed to look like. One end has been cut through and I think i'm missing some connectors with pins. It's in three pieces and mostly untaped from the factory wrappings. I have a 1966 T Bird tail light system with the rubber patch holding the sequencer, relay and switch, and the old harness that is in poor shape.
