Unless I'm wrong again, didn't the 75-76 have a wiper delay, and relay that mounted on the DS cowl brace?
If so, is there a diagram to get it wired back up, since my X mechanic messed that up also. I'm not so sure I don't have a aftermarket switch with no down position for it currently. |

All SWF wiper switches had 3rd position. 3rd position is obtained by breaking off plastic tang. HOWEVER the switch HAS to have 5 wire pins to make intermittent wiper work. IF you use the 6 wire switch you can have both intermittent and electric pump.
Intermittent wipers were not standard. They had to be ordered. You can update at any time. Check Classic Threads for information on wiring. |

What area is the plastic tang? |

Jeff Bowlsby has this instruction doc on his site that gave me all the info I needed to add intermittent wipers to my car. You need a harness to plug the relay into the existing harness. I believe Jeff sells those as well.

I have five wires that are coming out of the part that the relay plugs into that used to be hooked up.
Red, Brown, Green, Blue, and I think Black. The brown wire has one of those piggy back ends on it. Looks like the Red one may have, but looks like it may have broken off? |
