Sequential Turn Signals
Installation instructions

 Each module has five different colored wires. 

These directions describe connecting one module to the right side of the vehicle, the left side will be the same. Before you start, determine if you will need to replace any single filament lamp sockets with dual filament sockets. Some vehicles that have three-segment red lights per side actually only have two stop/turn lights per side, the third segment (usually the inner-most one) is a parking lamp only. A good example of this is the Pontiac Fiero. If you want all three segments of the light to sequence, you simply have to replace the single element bulb and socket with a dual element combination park/stop/turn bulb and socket. If you do not want to replace the socket, you will still be able to sequence the two stop/turn lights per side.

When I describe the lamps I may refer to them as inner, center, and outer or 1, 2, 3. The inner lamp will be the first to light, followed by the center, and then the outer. The connecting diagrams do not show vehicle wire colors because not all vehicles are the same. For the Pontiac Fiero and most other GM cars, the following list may be used:

Wiring method #1:

    Turn signals will sequence outward and continue to sequence until your signal is canceled. Four-ways will sequence. Brakes will sequence once and then remain on until the brake is released. This is the simplest and most common way to connect your modules. It does not require running any new wires, all connections are made at the light sockets. 
    The inner lamp remains connected to the vehicle's original wiring. The red and orange wires from the module get spliced into the Stop/Turn wire of the inner lamp socket. Connect the green wire to the stop/turn wire of the middle socket. Connect the yellow wire to the stop/turn wire of the outer socket. Connect the black wire to ground.
    Option: The orange wire can be connected to the red wire through a switch. When the switch is opened the lights will operate normally.

Wiring method #2:

     Your turn signals will sequence outward and continue to sequence until your signal is canceled. The brake lights will operate normally. If the turn signal is on while the brake is applied, the turn signal will sequence while the brake operates normally. The four ways will sequence. This method requires running one new wire from each module to the front turn signal circuit at the steering column or the front of the car. 
    The inner lamp remains connected to the vehicle's original wiring with no changes. Connect the red wire from the module to the stop/turn wire of the inner socket. Connect the green wire to the stop/turn wire of the middle socket. Connect the yellow wire to the stop/turn wire of the outer socket. Connect the black wire to ground. Connect the orange control wire from the module to the appropriate front turn signal wire at the steering column or front turn signal.
    Option: The orange wire can be connected to the red wire through a switch. This will stop all sequencing and return all lights to normal operation when the switch is open, and sequential operation will continue when the switch is closed.

Front Turn Signal Sequencing:

    Method 1 is aslo used for vehicles with rear turn signals that are independent of the brake lights (amber lenses as on the '86-88 Fiero GT), and can also be used for the front turn signals.  Turn signals and four-ways will sequence, brake lights will not be affected.
    

Two lamp sequencing:

    If only two lamps per side will be sequenced, the green or yellow wire can be used for the outer lamp. The green wire will provide the normal .1 second delay. The yellow wire will provide a .2 second delay which may look better for a two lamp sequence. The unused wire can be left unconnected and should be properly insulated.

Sequencing more than 3 lamps:

    If more than 3 lamps need to be sequenced, it can be done in two ways. One way would be to connect more than one lamp to each output of the module, being sure not to exceed 10 amps per output. This would still only provide a three step sequence, more than one lamp would illuminate at the same time. An electronic flasher will be required. If more than three steps of sequencing are desired, two or more modules can be used. The red wire of the second module would be connected to the yellow wire of the first module. This will provide a five step sequence where each of five lamps are illuminated independently. Three modules would provide a seven step sequence. Whenever two or more modules are used in series, a modified flasher will be required.

Notes for flashers:

    Most vehicles that have two or more stop/turn lamps per side will already have a heavy duty flasher that will work well with the sequential modules. If your signals flash too quickly and the lights go out before the sequence is complete (outer lamp never lights), then you will need to upgrade your flasher. I recommend a Tridon EL-12 electronic flasher which can be purchased at most any auto parts store for less than $10. If you have an '84-88 Fiero notchback, the stock flasher should work well with these sequencer modules.

Soldering is recommended for all connections, but crimp-type connections are also acceptable. All connections should be properly insulated with electrical tape or heat shrink tubing. Any unused wires should be insulated. The modules can be mounted with double sided tape or nylon ties, or they can be taped into the wiring harness. They are completely waterproof, so they can be mounted anywhere.
