I'm at the end of some rewiring in my '74 2.0. What I can't figure out is how the fog relay is supposed to work without a ground. I have studied the diagram and as far as I can tell the relay isn't grounded.
Can anyone give me a clue? I need another set of eyes and brain for this one. Thx. Thomas |

On the foglight relay, 86 goes to the foglight switch (gray-brown wire) where it is ground when the switch is pulled. 87a is not used on that relay, on other relays 87a and 86 are normally bridged.

Andy, is that terminal 31 on the switch that illuminates the switch light? That's how I originally had it wired. |

Andy, is that terminal 31 on the switch that illuminates the switch light? That's how I originally had it wired. 31 (brown ground wire) goes to 31 on the emergency flasher switch. 15 (black/blue wire) goes to 56 on the light switch. K (gray/brown wire) goes to 86 on the fog light relay.
