ok more electrical stuff...
disco2 installing 2 center hella 4k's on roof rack using separate 30A relay and oem aux light switch.
here goes...
1. +12V wire to pin 30: does it matter if it comes from battery or anywhere else?
2. pin 86 to pin 4 on lr oem aux light switch and pin 1 to +12V source(does it matter which source?) then what? this switch requires another source of +12V to pin 2 then pin 5 to ground(does it matter where?). or is the pin layout for this switch different? this switch has an on/off light indicator.
i still have to do my work lamps too but i'm stuck on 4k's.
please help.

I'm not sure about the layout of the factory switch but the relay I would use a 12-14 guage wire directly to the battery going to 30 on relay 85 ground 86 12v switch power from factory switch and 87a to hella 12v then ground hella
hope that helps if not let me know

ken,
i think my problem is in the factory switch pin configuration...
thanks

Han,
You said a DII oem switch. Is this the momentary (on only when pushed and held) switch like the DII fog lights?

Carl

By han chung on Thursday, November 08, 2001 - 03:11 pm: Edit

supposedly, it functions the same way as the oem fog light switch. you push and indicator light comes on and push again and light goes off. i don't know if it's momentary or not. the switch doesn't push down and click and stay inthe down position like the switches w/o indicator lights.

By Carl E. Cedeholm (Cederholm) on Thursday, November 08, 2001 - 04:07 pm: Edit

Yup, that's what I thought. You will find that the switch is only on when it is depressed. I had to get a special relay that stayed on till it gets another jolt of power to shut off.

Without that, you would have to hold down the switch to activate the light.

I have heard of people using a the clickable cruise controll switch.

I just went though all this.
Feel free to contact me off line if you want to hear about my tials and errors before making your own.

By David on Thursday, November 08, 2001 - 04:38 pm: Edit

Han, get a dII cruise control switch as Carl stated. It works perfectly...

By han chung on Thursday, November 08, 2001 - 05:10 pm: Edit

ok, i get now. cool, i knew it was the switch(the problem that is).

By ken on Thursday, November 08, 2001 - 05:59 pm: Edit

If it's a momenatary switch all you need is a lacthing relay. if you have fog lights you can use the outputs of those as they will already have the relays built in and you could use those wires to drive your relays. How many pins are on the switch? I'm sure you could make your own lactching relay with 1 extra relay (that is in addition to however many you were going to use in the first place) Depending on what the switch does all you have to do is run the output of the relay 30 back on to itself at 85. once the relay opens it will hold itself open then all you need to do is interupt the wire you ran from 30-85 with a relay when that one is activated it shuts down the relay. so if you have 4 lights I would use four relays in this manner and 1 relay to turn them off a total of 5 relays. You could put 2 lights per relay but I wouldn't.
I have 3 hella 4k on my bumper and I used 3 relays.

Use an AMR4138 foglight switch from a series 1 disco.

Hey Carl,

How's about I install your snorkel, you do my spots?

Dean

By Carl E. Cedeholm (Cederholm) on Friday, November 09, 2001 - 10:12 am: Edit

Dean,
How about I install your lights and you convince my wife to let me get a snorkel.

Ken,
Thanks for that info! That is very usefull for anyone wanting to do this with the Dll fog switch. I would love to see a wiring diagram if you had the time to draw one ;)

Carl

By ken on Friday, November 09, 2001 - 04:57 pm: Edit

Yes I could draw a diagram but I would need a to see a factory switch to see how it woiks to be able to dis-engage the latching relay. It's very simple and useful for many application. You could make a starter interupt for your car using the same principals. so that if someone tried to start your car the horn would go off and would not start. Unless of course you activated a secret switch. You can do just about anything with a relay.

Ken,
If I pull the switch soon I'll photocopy the circuit board for you. But in the mean time could you draw a circuit using a simple momentary switch?
I think this would be a good addition to the tech section. (and it will help me with Dean's truck)

BTW DEAN!! what happen? Scared to talk to my wife about the winch??

Anyway, thanks for your help Ken,

Carl

By Carl E. Cedeholm (Cederholm) on Friday, November 09, 2001 - 07:10 pm: Edit

sorry Dean, I ment snorkel.

By han chung on Friday, November 09, 2001 - 08:50 pm: Edit

it sounds like all dII's have evil current running when one tries to add lights...
carl, thanks for the info.
ken, that drawing would be nice for reference to all DII's trying to install lights... it's a freakn' nightmare.

Carl,
I'll work on her this weekend!
Gotta back me up on the winch too though!

Carl,

Kinda reminds me of what my wife once told me:

The important decisions in life are made by MEN.

The unimportant decisions are made by WOMEN.

What's important or not, that's decided by WOMEN!

By ken on Saturday, November 10, 2001 - 05:57 pm: Edit

yes I can but I don't know how to post it

O.K. you will need 2 single pole relays to make a latching relay with a momentary switch the first will control the lights the second will turn it on and off. so the first one I would duplicate for each light. you should have (5) pins on the relay 85 86 30 87 87a. first relay

1. 85 12v from your momentary switch can just be a pulse of 12v.
2. 86 a wire that will go to 87a of relay 2
3. 87 nothing
4. 87a wire to the 12v pos of your lights.
5. 30 12v wire directly to battery with a fuse.
6. jump a wire from 87a to 85

second relay
1. 85 12v from your highbeam lights
2. 86 ground
3. 87 nothing
4. 30 ground
5. 87a should have a wire going to 86 on relay one. you can have (4) wires coming off this one going to 86 of each of your relays.

How it works. when you turn on your highbeams it will send ground to 86 of relay one. When you push your momentary switch it will send 12v to 85 opening the relay. the wire you jumped from 87a to 85 will hold the relay open and you lights will stay on. to turn them off just turn off your highbeams. The reason I wanted to see the switch is if it has multupal pins the might be able to turn them on and off with the switch but this is also a good set up. also since I don't have a relay in front of me I am going by memory for the 87 and 87a positions on the relay my direction assume 87a is the on top of the relay. if 30 is on the bottom 87 above that then 87a above that. if that is not correct just swap 87a for 87 but I'm pretty sure I right.

hope that helps

Your the post master, could you advise Ken please?

By ken on Saturday, November 10, 2001 - 06:29 pm: Edit

carl looks like your on line now does the last post seem helpfull

By ken on Saturday, November 10, 2001 - 09:49 pm: Edit

After looking I did mix-up 87 and 87a just reverse those sorry it should look like this.

Just curious how your install went

By Carl E. Cedeholm (Cederholm) on Tuesday, November 13, 2001 - 02:21 pm: Edit

Sorry Ken, I missed your post on Saturday.
I was able to find a latching relay for my install (works great)...and I tried to guide Han off line on his install(still waiting for his results)
You post will be very helpful for me to wire Dean's truck, or for future lights for me.

Thanks for your help

By han chung on Tuesday, November 13, 2001 - 10:16 pm: Edit

carl,
don't know if you got my message... but i got some switches from a disco I and they work fine except for one little problem. i have both switches on separate wires and relays... everything separate... only thing is that (+) to relay is same source and (-) from all 4 lights same source too. don't think that makes a difference??? and (+) to both switch from one source; (+) runninglights to both switches from one source; and ground from both switches same source. am i wrong here?
result: when either switch is on, all four lights are on... i.e. when corner lights are switched, corner lights are full 100w on and center are dimmly on maybe 50w... and vise versa. when both switches are on both sets of lights are fully on 400w. like i said, don't have any wires crossed from switches to relays.
any input on this phenomena?
by the way, both lights/leds work fine on the switch.

By ken on Wednesday, November 14, 2001 - 09:59 am: Edit

Where are you grounding your light they should all have a common ground as you say they do. then ground them to the chassis of the car. 2.the 12v+ from the relay to the lights should be coming from #30 on the relay. all relays should have common ground directly to the chassis. all can have the same 12v source and should be connected to #87 and that should work if it doesn't then you need to find out which wire is "leaking" power back to the lights and use a diode to isolate it.

By Carl E. Cedeholm (Cederholm) on Wednesday, November 14, 2001 - 10:29 am: Edit

Han,
I'll check my email, but listen to Ken, he knows a lot more than me.
...so the DI switch fit the DII, ..and looks stock?

Very cool.

By han on Wednesday, November 14, 2001 - 01:27 pm: Edit

ok i gotta check my relay wires... thanks ken.
carl, i have the light switch set that goes in place of the coin tray. it slides right in and the set up takes 2 switches. looks pretty nice.
