Reverse light wiring

No reverse lights working, bulbs are present. I have found these two wires coming from the gearbox, can anyone tell me how to connect them and if I'm missing something.
Cheers

 

The other half of a fuse holder

 

Ha yes, I forgot that bit. Yes realised it's missing the other half, don't suppose you know where they connect?

 

There should be a connector on the nearside (passenger side if RHD) of the gearbox, fairly near the front of the gearbox. This is the reverse light switch. It has two connectors on it. Connect one connector to live (ignition live and fused, preferably), the other connector goes to the reverse lights in the rear light cluster, make sure earth is connected to the other side of the bulb. They should then work.

If you don't have the connector on the gearbox, there will be a blank plug instead, whip this out and replace with a reverse light switch (available at most of the VW parts suppliers) but be quick because once you take the plug out, gearbox oil will start to come out!

 

There should be a fuseholder connected to the black wire side of the ignition coil. Not the green wire side or the engine will die in reverse.
The picture you have is the other half of it.
And the rest is as above.

 

Looks like the wires are in place the gearbox end, so I need another half of the fuse lead and fuse into ignition live?
Then the other lead in my photo above connects to the light cluster, I'm taking it the nearside cluster? As you see on my photo above the bottom terminal already has a lead in it, would I double up on this, also where is the earth supposed to be?
Cheers, ps I'm very visual so a photo would be perfect.

 

Crimp a new fuse holder on, stick an 8 amp fuse in it and run it to the ignition +ve terminal, making sure it can't chafe on anything. Put the other lead on your reversing light terminal and check that the second wire goes up and over to the light on the other side. There's no earth: the earth connection is through the bulb holders.

 

Brilliant thanks, I'll order a fuse holder.

 

It's easy peasy, mate. You've got the switch in place already - hopefully it's working. Just make sure that any cabling before the inline fuse can't short on anything: the supply to the sign +ve itself isn't protected by a fuse. I cable-tied mine to one of the heater pipes to keep it out of the way.

 

Cheers nice one

 

Need to fix these on mine too so this is a very helpful thread!

 

Me too

Where on gear box should I be looking to see if I have switch/wiring installed? Thanks

 

Left hand side, up by the nosecone. Should be easy to spot. Blanking plug if there's no switch.

 

Thanks @snotty
So in the picture below of a lovely clean box (definitely not mine!) it is the round thing up front end about third the way up. Looks like it might have some spade connectors on. Do all gear boxes look similar and have switch in same place? Mine is attached to a type 1. Thanks

 

That looks like it. I forget what mine looks like. Anything up that end with electrical terminals is the reversing light switch. It's operated by the selector linkage inside.

 

...or it may be the ejection seat actuator. I forget...

 

Is this the same for a type 4 engine??

 

Yes.

 

Yeah found it. Covered up by loads of gunk. Just couldn't find Allen key set so that's a job for next time!!

 

Cheers guys fixed.
Less than a 5 minute job, someone obviously couldn't be bothered replacing the other half of the fuse holder!
