I would like to wire my series 79 Toyota headlights to kill when the ignition is switched off.

What do I need in the way of relays and how do I wire it up.

Chris

Possibly less technical, I put in a "headlight left on" warning from dic smith ($10) I kept forgetting to turn mine off. This has an audible/light warning. Works for me.

Hi Chris
I was going to sort of try and explain how i would have done it then the Parkers came to mind and I thought this getting harder the more I thought about it then I remembered the little warning buzzer I bought and fitted to my Subaru in the 70s and they still are on the market but if you zip into any good Auto-Electric shop they will have one installed for in no time, that would be much easier way of remembering to turn off the lights than whackin your self in the back of the head .

Hi Chris, the 70s Toyotas have a pretty straight forward wiring set up for the headlights.

The headlights are negative switched but the common wire from each headlight goes back to the fuse panel.

From memory, there are two fuses for the headlights.

Try turning the headlights on and pulling the fuses and see if the headlights go off. This may seem like the obvious but Toyota’s have some strange headlight wiring.

If the lights go out then all you need to do, is fit two relays, one on each common wire behind the fuse panel. Then one side of each relay’s coil wire to earth and the other coil wire to one of the ignition circuits, also found behind the fuse panel.

With this set up, when you turn the ignition on, the relays will energise but the headlights will not come on until you turn the headlight switch to on.

When you turn the ignition off, the relays will switch off as well and if you have left the headlights, they will be turned off. I take it this is what you are after.

If this is what you want, post back and I will give you more detailed wiring info.

Cheers

Thanks for the info, I think I will just go for a lights-on warning buzzer.

Hi again Dermie, My RR is a diesel and the D3 is a V6 petrol.

I like the extra grunt the petrol D3 has over the TDV6 D3 but the RR still has more grunt than either D3 and gets 9.1/100 on trips. The best the D3 gets is around 12/100 on a trip so if you have the extra $8k and you are planning to do a lot of driving, go for the diesel.

If the fuel prices had started to rise when I was buying the D3, I would have probably gone that way.

I don’t know how soon you want the D3 but I believe there is a twin turbo TDV6 D3 coming soon. Others may have more details there.

Don’t confuse the 2000 RR with the new Land Rovers as far as electronics go.

There were and are lots of problems with the pre Mk3 RR but the Mk3 had the fortunate advantage of getting BMW electronics instead of the Lucas crap.

the D3 goes even further in that it also has had some Ford input to push the BMW style electronics to even better performance.

I’ve had quite a few warranty problems with the RR but not one has been a direct cause of the electronics and in a number of cases, the electronics has warned of potential problems before they occurred and in my opinion, thats what modern automotive electronics should be capable of doing.

The D3 comes with a 3 year/100k warranty and for around $1,500 you can, at any time while the original warranty is valid, extend the warranty period for another 3 years/100k.

Hi Chris, Sorry about the above post, that was for another thread.

Anyway, I was going to suggest that you use a buzzer but as your lights are negative switched, it’s a bit tricky to wire up.

It’s been some time since I owned a Toyota but if the parking light circuit is positive switched ( I don’t think it is ) this would be the place to put the buzzer.

Cheers and have fun fitting it.

the 100 series ( also (80?) crusiers switch off the head lights when you open the door.

Requires one to operate ingnition and they will switch on, or on the headlight stalk, switch off and then on againe if ingnition off.

Works for me...when being driven, mine are always on day or night

If you are going to make ANY modifications to your headlight wiring, make very sure that it won't be less reliable than it is now. All connections well secured, cable ties to prevent vibration causing wire fatigue failure etc.

Imagine driving on a moonless night around some tight bends - and suddenly evrything goes black !!!! (If it ever does happen, flick on your turn indicators - not much light, but better than nothing).
