"Lights On" Buzzer

[Junglist]

OK, that's the pos connection sorted. Is there a door-open fuse to connect the neg to? If not, where's the easiest place to connect the neg side of the sounder?

[Funky Diver]

On the door switch... like the one near the fuse box, but on the drivers side.. It IS the Negative side. I'll take a look at the wiring diagram schematics and see if there's another point you can use.

edit : You're looking for the black wire that goes to the drivers side door switch.

you'd need to take the earth off the back of the switch - earths aren't fused so you won't find it in the fuse box

personally i'd take the +ve from the dash lights behind the radio. nice and easy to get at

[Junglist]

The back of the door switch? Isn't that tricky to access? And to route wire to? It's in the door frame under the a pillar isn't it? I'll have a look tomorrow.

[Funky Diver]

You just need to attach to the wire that leads TO the door switch. The switch itself is just a mechanism for making a contact.

[Junglist]

Yeah but where's the easiest access point to that wire?

I dont think its a good idea to wire it into the headlight feed, if you think about the voltage and current going down that wire to feed the headlight (all though a 20 or 30A fuse), it might end up cooking a low power buzzer or in a worst case setting it on fire. If you think electricity takes the shortest/easiest route to ground, a small buzzer drawing milli Amps is alot more attractive than a pair of 60w headlights.

I'd say you'd want to take the signal from the indicator stalk where its low power and use an inline fuse too.

It might not happen, but thought its worth throwing in for discussion.

Edit: You should take the signal from between the headlight switch and headlight relay - Not after the relay in the high power part of the circuit if that makes sence..

[Nate]

unless you've added a headlight loom upgrade, there ain't no headlight relays on the rocco. it all goes straight thru the switch. you'd also be better wiring to the sidelights or dash lights than the main headlights. sidelights will make the battery go flat too

just undo the switch and pull it out. there should be a bit of slack in the wire. either solder your new wire to the existing, or cut the spade connector off and put both wires into one new spade connector. then poke your new wire into the hole and fish it out in the footwell.

Agree with the headlights... hence hte suggestion for sidelight circuit

Junglist, this is the set-up that I was talking about yesterday with the diode.

Ashtray light should work just as well as the sidelight (I think Nate mentioned).

bloody done it again!jumped in the car,went to start it and the battery was flat.not amused.did anyone ever find out if the golf relay worked or would anyone like to sell me the relay that works?im fine with mechanical stuff but electricals are witchcraft as far as im concerned so plugging in a relay would suit me better than messing about with wiring....

Ok after some digging i have found this info and i think it will solve the problem of the fog lamp not working as you know the 292 relay was never designed for the fusebox in the sciroccos, so when they did start the buzzer it was an addon onto the top of the fusebox and wired in separately. I took this information from vwcaddy.com because you have to register to view it but i think its what everyone has been after.

Mk1 ‘Lights left on’ buzzer mod for pre-'89 fuseboxes

Someone else posted up a thread about the plug-in relay mod for the late (post '89) fuseboxes. However, after messing about with the relay and wiring for a bit I've got it working on the earlier fuseboxes

I’m not an auto electrician by any means. This is what I did to get the buzzer working on my ‘83 Golf Gti. Feel free to do the same but I can’t / won’t be responsible for any problems you may encounter should they arise

A - Find a donor !
The relay is a Seat part so you’ll need to locate one of the following Seat produced cars in the breakers :

Seat Ibiza 6K (’93-’02) or it’s Cordoba / Vario variants
Seat Inca van (’95-’03)
Caddy 9K van (’96-’05)
Polo Saloon / Estate (not hatch) – similar years to the Caddy van




B – Get the parts
The fusebox can be found above the drivers side footwell on the donor car. You’ll need to take off the drivers side glovebox and remove the cardboard undertray to get at it properly. When you do you’ll see something like this. The relay we want is top left



Carefully remove the relay from it’s plug. If you just pull on it then it’s likely that the relays cover will just come off. Wiggle it and maybe try and get a screwdriver behind to lever it off

Lift the fusebox from it’s mounts by pushing up the clips on the sides, then drop the box down

You can then take off the relay holder from the top of the fusebox. You need to push a screwdriver under it and lever it up while pulling it towards you



When the holder is free spend some time tracking the wires back to the main loom and cut them there. You want as much wire on the plug as you can get as it’ll make things a bit easier later

When done you should have this :



C – Wire into your Mk1
You’ll need to isolate the battery before doing any work. When you’ve done that, remove the passenger side undertray and drop the fusebox down. Happily the Seat relay holder will slide right onto the top of a Mk1 fusebox. Pick your preferred location !



Three of the 4 wires you’re looking for on the Mk1 loom terminate at the red plug on the rear of the fusebox. These are grey/red, grey/black and black/yellow :



You need to connect as follows :

white/red on relay holder to grey/red on the Mk1 loom
white/black on relay holder to grey/black on the Mk1 loom
black/yellow on relay holder to black/yellow on Mk1 loom

How you connect the wires is personal preference although Scotch Lock are fine for this IMO.

The only other wire to connect is the brown/red on the relay holder. This connects to the brown/white door pin earth switch on the Mk1. I extended the wire from the relay holder, passed it through the body of the car and connected directly to the door pin switch (‘piggyback’ spade connector), but upto you where you trace the wire and attach.

Fit relay to holder



Just have to refit everything, reconnect battery and test ! The buzzer will sound when the door opens if the lights are on but the ignition is off. It shouldn’t sound under any other condition.

As said, this got it working on my Mk1. If you try it let me know how you get on.

[Nate]

i think we've got one of the listed donor vehicles in work, if it hasn't been scrapped today. i'll have a looky and grab it if it's there :)

Just to inform that the buzzer relay for the mk3 golf is number 36 but unfortunately sits in the fusebox so you wont be able to remove the relay socket as well, thus requiring you to wire it all in directly from the pins on the relay, which is what i am going to do
