Turn-Signal Options

We get a lot of questions about turn signals and brake lights.  There are two options in our standard front-engine configuration: Mechanical Multi-Filament and Mechanical Single-Filament. This is where there is sometimes some confusion. In both cases, this is where you use a traditional steering column with the canceling mechanism built in. This can be an OEM column or one from an aftermarket company like IDIDIT or Flaming River. In both cases, the mechanism in the column turns off the turn-signal action when the steering wheel returns to the center position.

The mechanical column, multi-filament configuration should be used when you have separate filaments in the rear of the car for the turn-signals and the brake lights. These could be completely separate bulbs or different filaments in a multi-filament bulb. The inputs to the MASTERCELL control separate outputs for left & right turn-signals plus the brake light.  There is a good rule of thumb for multi-filament turn-signals: if your turn-signals are amber, you should probably be using the multi-filament configuration.

The mechanical column, single-filament configuration should be used when the brake lights share a common filament with the turn-signals in the back of the car. Remember that you need to look at the filaments, not the bulbs. In this case, the MASTERCELL inputs will activate the left and right turn-signals as directionals. You only wire the left and right turn-signal wires to the bulbs. No brake light output is required. For the brake light, the left and right turn-signal filaments light together.

Once you figure out what you need in the car, you just pick the inputs that you need and wire them to the column. This schematic will show you how to wire the MASTERCELL inputs to the GM, IDIDIT and Flaming River columns.
