I am building a 914 track car and we are trying to wire back up the wipers and I can't find the relay. I didn't see a relay in teardown and don't see anything like the one mentioned in the left-over parts bins.
I just wanted to wire the motor direct so I can toggle the wipers on and off with a switch (sans relay) but I can't find any diagrams that don't involve the relay and my attempts to "hot wire" it have failed. Any ideas, can't I run switched 12v+ to it and ground the necessary wires to test and/or run it this way. I understand the wipers would not return to the down position automatically but just need them for occasional mist/rain at the track. Any help you can offer is much appreciated, 3 weeks till first race. -Daryl |

The relay should be on top of the fuse panel. The fuse panel drops down by removing a couple of screws.
Using a relay is generally the best idea; it not only allows for control of the wipers the "normal" way but it also takes some of the electrical load off of the wiper switch. (I think...) --DD |

I just wanted to have something if they get rain while we are on the track. |

There is no wiper relay unless you have an intermittent setup. Wiper switch controls the wiper motor.
You should be able to jumper to one of the leads via a switch to make it work. If you want it to park itself then it's a little more work. |
