PostPosted: Mon Aug 02, 2021 7:00 pm    Post subject: I need help finishing up my wiring. Reply with quote

I thought I had documented my wiring well enough to be able to reconnect everything after changing out my dash, I was wrong.

I have about 3 wires I need help with.

Where does the red wire that comes from the Hazard light #30 spade go to?

Where does the white wire with 2 black stripes from the headlight switch #56 spade go to?

And what size fuse goes in the wire from Fuse #8 back to the Westfalia cabinets?

Any help is greatly appreciated!

Front dome light. White fuse.

Awesome, I thought I had figured it out and you confirmed it. The only issue is I must have mislabeled other wires going to the relay. What colored wires go to S and 30 on the relay?

Ok. My #9 fuse blew. There are only 2 wires going to it. One from the light switch and the other back into the main bundle. Does anyone know where I should look for the issue?

S will be a Brown with White stripe and there is not a 30 terminal on the relay. There is a 30 terminal on the headlight switch and it gets a fat red wire.

This is the relay I'm trying to connect.

Which fuse dose the red wire from terminal 30 on the light switch connect to?

Terminal 30 on your relay is just a retaining tang, and has no electrical connection. On the European version (and on replacement relays sold here), that terminal needs to be connected to unfused 12 volts to operate properly.

Yep...same connection for #30 on pretty much anything non-bus that uses it....and that relay actually started its life in the 411 and 412 cars as the high beam relay in 1968....hence the 411 part # prefix! Very Happy

Thank you! There is so much I have to learn and electric is my weakness.

Does that work for a 1978? That's a nice diagram. I can almost understand it.

I also have this loose white wire with 2 black stripes. Any idea where it goes?

The fuse block diagram does NOT apply to a '78 - sorry. On the '78 schematic, fuse #9 is a spare (normally unused). Better see what is connected to it...

From Technical (click to enlarge):

The black/white wire could be the one that runs from the ignition switch to the door buzzer...

I think you are correct. I looked back at some pictures I took and it looks like it connects to the same door buzzer that a grey wire connects to. So it's not being used at the moment.


Right now my #9 fuse is connected to the wire that leads to the #30 spade on the light switch. That doesn't sound correct.

I'm trying to read that wiring diagram. Where is the fuse box in that?

Fuse 9: top of columns 7, 8.
Headlight switch: columns 21-28.
