I want to fit a warning buzzer that reminds me to turn my lights off when I turn the ignition off.

Obviously I need a feed which is only live with the ignition off and the lights on...?? Any one else done this or have the magic answer??

Your headlights should shut off when you pull the key. But the car is designed to leave the running/marker lights on in various conditions in the event you have to leave it sitting on the side of a dark road and don't want to get hit by some moron.

However, my US '88 951S will still buzz if I have left it in a running lights on position when I open the door. Either your buzzer on the fuse board is broken or Porsche wired the European cars different.

 

I think European cars are slightly different to US cars as we have a 'driving light' combined in the fog lamp unit which comes on when you turn the switch to the first position, the second position raises the headlights, do you have a similar function?

Perhaps the warning buzzer simply isnt working on my car then...? <img src="confused.gif" border="0">

 

Do you have a seatbelt buzzer as well, or not? That and the light buzzer are all part of the same relay. The PO of my car removed it and tossed it in the glovebox. I forget which relay it is, check your owners manual.

Hopefully that fixes the problem for you!

There is a relay in position G8 listed as 'Warning Buzzer' which is missing. That must be it?

I'll buy it tomorrow and see!

 

Stan, my '88 951S has G8 listed as the gong/buzzer relay but it is actually G16 that is the gong. Also has some holes punched in the top of relay case to let the sound out.

Not sure what you mean by "driving" light in switch position 1. Is this some sort of city light? Anyway, we don't have it on North American 944s.

 

i used to have eurospec '87 and now have US spec '88 951.Wiring is different.Euro spec car does not have this "gong relay".Sometimes this "gong" is not so nice.It is hooked at lest to doors,lights,seatbelts etc.Last summer i took it off and used car without it.I installed it back last spring, guess iam used to it now!

Dont know what city lights are but we use driving lights (also called side lights, though they are not actually on the side of the car!) for driving at dusk times or perhaps when its gloomy and raining - basically whenever you want to increase visibiity but its not actually night time so you dont need headlights. Hope that makes sense - perhaps its the same as city lights...

Relay G16 is also not used on my car but this relays also seems to have something to do with the catalytic convertor, which my car has never had.

It looks like if I plug a relay in though it would work as you can see the metal contacts underneath? Is this a good idea?

Sorry for the long post. <img src="confused.gif" border="0">

Stan,

Can't really help with your gong problem but an curious about this G16 relay ... You mention is has something to do with the cat - could you be more specific? Does it tell the car that it is cat equipped and therefore instructs the DME to use a signal from the O2 sensor? I'm just trying to find a solution for something that's been bugging me for nearly 3 years in that even if I solder in the O2 sensor to the DME, it basically ignores it anyway (Euro '86 951 - no cat nor O2 sensor orginally).

 

Gary - I have no real idea what it does! On the underside of the fusebox lid the description for relay G16 reads: 'gong/catalytic converter warn.' I assumed its for when the cat is not working properly but others on here say it controls the lights on warning too. I'm phoning Porsche Club GB's technical guy later on today for further info so I will let you know...

 

Stan, city lights are typically an additional little 5 watt bulb in the headlight that Europeans have. Isn't of much use other than as a marker light for other drivers to see.

I don't know if your G16 relay plug is actually wired up to work. Guess it wouldn't hurt to try just be sure you watch it carefully in case there is a short - some of the relays are in front of the fuse and will actually start on fire if you have a short.

Porsche did not make one universal wiring harness for all the cars sold into various markets. So better talk to some local folks and see if they have the wiring diagrams and know if the gong is functional. Also remember you are missing G8, what ever that slot is supposed to do on your car.

Appreciate it Stan, thanks very much

Also an interesting comment about the different wiring harnesses - I hadn't realised this since I thought that the 944 was a "world" car (albeit, with slightly different configurations).

 

I spoke to a guy called Steve Kevlin at the Porsche Club (UK rennlisters will probably have heard of him) and he was unsure as well but said he would send me the wiring diagrams to look at. How much help these will be to me is debatable but if any of you guys are interested I will scan the relevant parts and post them here.

On a different note, for those who remember, my brake problem was finally resolved the other day and was traced to a loose pipe on the inlet manifold with a hardened o-ring. Actually quite impressed with the standard set-up, better than I expected so I may not bother with that BR setup but just upgrade the existing with racing fluid, 968 ducting, Pagid Orange pads and braided lines.

 

Stan
The label in the fuse box cover differs from reality.
There is a note about this in the manual (but I cant find this anymore).
The wiring diagrams seem OK.

The buzzer should make noise when you open the door (with key out), at least mine does.
Signal is picked up from the driver side door switch.(left in my case)
These are identical to the (good old) beetle so simple and outdated design, mounted in the door post between the hinges.
The switch body is aluminum, will corrode easy, but is easy to fix and cheap to replace.
Checking this might solve it.
To get at it, remove the screw and pull the switch out. You need an philips no 2 screw driver
