Hi, I'm pretty new to this, but am the proud owner of a 66 beetle, albeit with 12v and 1600 engine conversions. And there may be the problem. My wiper doesn't currently work, and contrary to any wiring diagrams i've seen, there are only 2 leads from the original dash switch to the motor which has a choice of 4 terminals. I've had the motor out, and got it working on terminals 1 & 4, but as soon as i reinstall it in the car, it blows it's fuse. Can anyone help?

You're right, it should have four wires, even on a single speed 6 volt system.

From to fuse---->----54 on switch------->-----54 on motor
54d on switch------->-----54d on motor
31b on switch------->-----31b on motor
31 goes to earth from both the switch and motor

Thanks for that. I'll take the switch out and make sure there isn't another terminal or 2 hiding away somewhere! At least I know where they should be going, and that my switch might be faulty.
