Yet Another Turn Signal Question(s)

[ray_mcavoy]

Hi WTexChevy,

The factory "single indicator" setup has both terminals of the single bulb wired to the switched side of each turn signal circuit. In other words, the single bulb gets power from the side that's flashing and grounds through the side that's off.

So most of the wiring should already be there to convert over to a left/right indicator setup. Just take the dark blue wire (possibly with a white stripe) off the existing single indicator and hook it to one side of your new RH indicator bulb. Ground the other side of that indicator bulb. Similarly, take the light blue wire off the existing single indicator and hook it to one side of your new LH indicator bulb and ground the other side of that bulb.
