Replacement Wiper Motor Wiring Question

[TurboFlash]

I'm replacing the original wiper motor on a '79 Super Beetle. I thought it would be a simple plug and play operation. But there appeared to be more wires than what should be there.

Old plug for wiper motor that connects under the steering column. Not sure what that brown wire is there for, because the new plug doesn't have a wire in that slot. It goes to the fuse panel.

New plug for wiper motor. No wire in the space where the brown one is in the original plug.

This black wire come from the wiper motor, through the firewall and is connected to a black w/ green stripe wire that going to the fuse panel. Not sure where this wire connects on the new wiper motor.

Fuse panel, notice the brown w/black stripe wire and the black w/ green stripe wire going to it.

New starter... I assume the brown is a chassis ground?

Not sure what this blue wire is for. Could it connect to the black w/ green stripe wire that connects under the dash and goes to fuse panel?

Thanks for the help!

In European Automotive Wiring, brown is ground.

I understand. But what is the blue wire for on the new wiper motor?

And why are there additional wires in the factory plug that go to the fuse panel that the replacement plug doesn't have?

The '79 Super Beetle came with intermittent wipers. The brn/blk wire goes from the switch to the relay in the fuse box. You have to have the right wiring or the wiper motor will not work unless you bypass the relay with a jumper. You may be better off just getting a good used wiper motor with the original wiring.
