So has anyone done the wiring for something like this? I already have individual switches linking the side-lights switch (fuse) to the relays.
TIA

I am sure I can help, I own an alarm shop. I need more details tho. Are you talking about the stock alarm? Do you have relays controlling your rack lights? What model/year do you have? Post some details of what you have and what exactly you want to do and I can whip up a simple diagram for you. We do this stuff all the time.

Stock 2001 D2 SD. The alarm has NO motion sensor like the SE model does. When it sounds, the horn blasts and the headlights flash (I think, correct me if I'm wrong on this please someone).
The lights are on three separate relays, leading to three switches inside the cabin. They switch the current directly from the battery via inline fuse, and are controlled by a thin wire from the side-lights fuse on the fuse box under the steering wheel area, to the cabin switches, to the relays.

Dean, I don't think you can still use the word "stock" with your truck... hehehe

Ok - for all people OTHER THAN pine barrens kids, this is actually a serious question! |

You will need some sort of a deiode in there somewhere to keep it from back feeding when you actually turn the rack lights on. Aside from that it should be cake...

The main question is this: Does the computer control the signal lights? Or do the steering wheel controls also do this independently? I don't want the lights to come on when I signal, or when I turn on the hazard indicators. |

Dean,
I know nothing about the LR alarm, and you know my philosophy about leaving Lucas alone, but you could hook up a relay and a manual switch to the lights.
When you arm the alarm, hit the switch and any activaion of the lights will trigger the roof.
Just don't forget to shut the switch off....hmm... or have a circuit that disarms your roof lights when the engine is runing.

I'm not an expert by any means, but common sense tells me that the alarm's computer sends a signal out to flash the sidemarkers. Find that output wire. Get a relay, wire it from the battery to the lights and use the alarm output wire (tap into it) that you find to trigger the relay. |

I agree with you Kingfish, but I'm glad it's Dean looking for that wire, and not me. |

I think this idea will work, but I agree with Kyle that you will need a diode or something to keep current from flowing back into the alarm computer when you are using the lights under normal usage. |

as an alternative, why not mount a couple of small strobes on the roof rack and triger them with the wire running to the side marker. |

But we don't want the lights coming on when we're signalling! That's the problem.

Somehow somewhere there should be a way that the alarm triggers the markers that flash and the horn. There may not be a separate wire for these going to each item and if not, the above will not work. In that case, you will have to explore to see if there is any type of auxillary wire like in an aftermarket alarm. Did you check with the RAVE cd yet? I'm not even sure where the alarm brain is on a Disco, but maybe there is some sort of trigger wire coming out of it that could be used to fire a relay. |

Just hook them to a relay using your blinkers as a trigger for one side of the relay. Then you could do 1 of two things
1 the other side of the relay you could go to the ignition wireThe ignition wire rests at ground and is pos. when on so when the car is off it will be grounded. and the blinkers will send the 12v to the other side of the relay making them blink. In this senario if you use you hazzards while the car is off the roof racks will blink.
2. find the alarm unit. There should be a wire that is only pos or neg when the alarm is armed. there should be a neg. "in" from the the doorlock tumbler this would be a good wir to start with. Use this wire for one side of the relay and the blinker for the other side. Of course you may need two relays in case you have to invert one of the wires from neg to pos. In this senario the roof rack light will only work with the alarm armed.
That being said I wouldn't hook my fogs up to a flashing source. I might be wroung but I don't think the thick filimantes in these light like to be turned on and off constantly. I don't know just a thought. |

Ok, here it is. I drew up a diagram that will make your external lights flash with your OEM alarm system. If done correctly your roof lights will not flash when you use your blinker when driving and you don't need to track down your OEM alarm control unit.
Two possible problems you may encounter if you do this.
1. Like Ken said above, your roof lights may not like being flashed and their lifespan may decrease by doing so. Fortunately, they only flash a few times when arming the alarm and when the alarm is triggered (and hopefully that will not happen often!)
2. If your alarm were to be triggered many times over a given period without starting the engine or charging the battery, your battery could be significantly drained (assuming your roof lights draw a fairly high amperage).
Here is a link to my diagram.

That is exactly what I outlined in senario one of my previous post. (althought great diagram) the only problem with it is the hazzards will still flash the roof lights when the car is off.

Although I don't know how the circuit works; but mabey if you cut the blinker wire and add a diode then tap your 86 wire behind the diode so you isolate the hazzards from the blinkers. That might work.

You are right Ken. I suppose you could put an on/off switch on the wire from the turn signal in the event you needed to use your hazard lights.
If you wanted to really be McGyver you could wire an on/off relay right after the hazard switch that would shut off the roof light flasher but a simple toggle switch would be much simpler.
If you want to automate the hazard switch bypass feature, Dean, I could work up a diagram for that to, let me know. I'd be happy to. |

Well, I just went out and checked the wiring at my hazard switch and all the outputs flash so there you couldn't just wire the output to a relay to shut off the roof light flash. You would have to make a latching circuit and I really don't think that this accessory is worth the work.
I recommend a on/off switch for the turn signal input for the roof light flasher but if you really want to auto deactivate the roof lights with the hazard switch we could make it work.

Shane, Ken and all,
Thanks for the kind help, and that diagram is great Shane. But I'm not going to do this if the lights will flash when I arm the alarm - I'm not sure of the legality of some of the lights I have and I don't want to flash them too much either But there should be a similar way that uses the horn wiring, since the horn and the headlights both work when the alarm is, well, alarming. Perhaps when the horn is on but the ignition is off, that would be fine. The horn does not sound when I arm the alarm.
Thanks again

Sure, you could use the horn circuit in place of the turn signal wire. You would need to tap into the horn circuit near the horn (after the OEM horn relay) so it will be a positive pulse. The horn circuit is negative coming out of your column. Wire the rest the same as the diagram and it will work and shouldn't flash the lights when you push the horn button unless the key is off.
Of course you may still want an on/off switch on the system to shut it down if for some reason you want to kill it.

Use the diagram that shane posted except instead of 85 going to the ignition wire take 85 to the horn output wire. The horn and blinkers pulse at the same time. The blinkers are 12v pos. output and the horn is neg. output. when your alarm goes off it will activate the relays. both the blinkers and the horn will have to go off to complete the circuit.
Now with that being said if your car is running and you have your blinkers on waiting for a turn and honk your horn at the right time your rack will light up. If you can't live with that then cut the wire from 85 (between the relay and the horn) and add another relay. The wires that you just cut put one at 30 and the other at 87a then put 86 at ground and 85 at the ignition wire from diagram 1 from shane. Now they won't light up with the car running. You would have to have car off hazzards on and honk the horn to make them flash witch would never happen unless you tried to do it.
Let us know if you actually do it. It should be pretty easy just use the diagram that shane posted or if he reads this post mabey he could diagram this senario for you. |

This is getting pretty crazy but here it is. A diagram with Ken's mod
I put a few comments on the new diagram regarding possible problems/issues I thought of. Taking #86 directly to the exterior horn is still a viable option and much simpler in my opinion.
All of the methods should work, you just need to decide which drawbacks are acceptable to you with each method.

In the diagram in your last post you only have one relay. My method requires two relays. one relay with blinkers at 85 and horn at 86 to control the lights. Then another relay wired as you have yours in the digram to intecept the horn 86 pin on the first relay so that the circuit won't work when the car is on. The diagram you posted will work but will leave Dean without a horn when the car is on.

After my last post I tought about your diagram. You managed to do with one relay what I was doing with two.
I was thinking that you were actually cutting the horn wire to make that circuit. Dean, Shane's diagram is perfect just remeber that you tap a wire on to the horn wire and that is the wire that gets cut not the actual horn wire. |

Guys - many thanks again for your help. I'll look at it this weekend if I have time. The main reason for all this is that I generally have a truck load of equipment in the disco that I don't want to get stolen. I can generally see the roof rack from just about anywhere in a parking lot (you know, with the tires and lift) but I can't see the headlights. And the alarm sounds like every other bugger out there too.
Another little project I might also do is link the courtesy light function (headlights stay on for 30 secs) to the rear-facing roof rack lights, since I have a dark driveway and always park facing away from the house. I'll figure this out -should be something similar.
