Four wires to ign. switch, which one is which?

[nikwho]

I searched with no avail. I need to know, of the four wires running to the ign switch, which is Ign., Bat, Acc and starter?

Thanks!

Just found this, I think this'll do. Thanks

So, I am sure that all of the information that I need is in the wiring diagram listed above, I cant quite make sense of it. I have a new ignition switch and it has a Bat terminal, Ign. terminal, Acc terminal and a starter terminal. Can anyone offer me any electrical help?

[nikwho]

looks like the starter is the Red wire with a black stripe, Battery is the all Red wire, black with yellow Acc., brown also to Acc, and the all black wire the Ignition???? I'm kind of lost here. sorry!

It might take more than 3 minutes of studying the wiring diagram to figure it out. Big red wire from the battery via the starter solenoid and the light switch (shown on the schematic) goes to your Bat terminal. On the schematic, follow the small black wire from the coil to the fuse panel and then to the D ign/starter switch. That's for your Ign. terminal. And then there is the big red/black wire going to the starter solenoid that connects to your Starter terminal. It's all just like the schematic.
The difference is that a bus switch had no Accessory position. And you don't need to hook anything up to it on your new switch. However there are some items that are nice to have hooked up to the Acc terminal. But if you had difficulty reading the schematic and figuring out which wires go to where on your new switch then forget about wiring anything to the Acc. terminal.

Can anyone help me out with what to do with the black wire with a yellow stripe and the brown wire?
I see the black/yellow wire runs up to the light switch and the brown wire runs to the door contact switch for the buzzer. If installing an aftermarket switch, I think I can just leave the brown wire DC'd, but what role does the black/yellow wire play in the headlights?

Thanks,
Nik

The black/yellow wire is for the VW load-reduction-on-start feature, i.e. it powers stuff that would normally be on the
Ignition (#15) circuit, but is temporarily shut off when cranking the starter. It needs to be connected to the Ign terminal also,
or otherwise connected to the Ignition circuit.

The brown wire does not power the dome lights, its for the key-in-ignition-and-door-open warning buzzer. If you want that
feature, you'll be the very first and only one I've heard of. No harm in just leaving it disconnected.

Ok, I'll start by saying that I was sleep deprived when I was asking about this the other day. I swear that I am not as dumb as I sounded in my previous posts. haha. Sorry. brown will stay disconnected. just radio will be on acc switch. Now, with that said, I wired the switch as described above and when I turned the key on, the starter runs in the on position. the big red wire is run to the BAT. terminal, the red/black wire to Starter terminal and the black wire to IGN.

Sounds like it's wired correctly so the only logical answer is a bad switch, ever considered just using the real VW parts and avoiding all this?
