Used this information to install my 73 Tach into my 74 car:
You would add two wires from the emergency flasher switch to the bulbs you will use (green/black and white/ black). These are the same wires and colors leading out to the turn signal bulbs at the four corners of the car. You will modify the existing blue/white wire to extend to the other side of BOTH bulbs. The blue/white wire terminates at the flasher relay itself. Weird thing is when all the wires are connected to the hazard switch, neither indicator works for flasher or turn signal. If I unplug the L or R from the hazard switch, both turn signal indicators work as they are supposed to and one of them lights up with the hazard (whichever one I didn't unplug)? I've already switched out the hazard switch. (IMG:style_emoticons/default/WTF.gif) Newer Update: All works if I detach the blue wire w/ white stripe from the turn indicator bulbs and instead install a ground to them. Guess I'm going with this solution rather than the diagram above indicating I need the two blue/white stripe (or, as indicated below, take the blue/white wire off of the flasher at terminal K and connect the wire to ground). |

(IMG:style_emoticons/default/WTF.gif) You Wrote: "If I unplug the L or R from the hazard switch, both turn signal indicators work" Do you mean if you unplug either wire from the bulbs to the hazard switch, they both work? If so, you have a wiring error. Looking at the diagram you provided, if either wire from the bulbs to the switch are unplugged, then current cannot flow through that bulb and that bulb cannot light up. |

Hmm... after further playing it seems that the hazard switch making the indicators blink is the issue. The turn signals work (power comes from the turn signal, not the hazard switch) in all cases. |
