Outer Limits 4x4 Board

i bought a set of spotties and am trying to install them right now but they didnt come with a relay. i think i can install them no probs but i can find the stock sierra relay. is there one or do i have to go out 2moro and buy one?
thanks

i just hooked them up to a switch and to the battery with a fuse in the cable and had a little led that would turn on when it was on

There was a post a little while ago with an easy to follow diagram. Do a search for headlight upgrade and you should be able to find it. And yeah you will need a relay to make em work

What about your high/low beam switches?

Use a relay.

For the sake of a few dollars from Repco or even an auto sparky, it's worth doing the job properly.

Tap the high beam +ve for the relay trigger.

i should be right with doing it but my question was is there a relay already in a stock sierra. coz the normal sierra headlights are off when the current is flowing to them so i figured theres got to be some sort of relay doing this, if u know what i mean.

if theres not one there ill just go buy one.

There's no relay in a stock sierra loom for headlights.

do a search - there was an excellent explanation of how sierra headlights work and how to wire spotties about a month ago.

Have a look at http://users.mrbean.net.au/~rover/headlamps.htm

I found it very good info.

THAT WON'T WORK.... Try this..

On the rear of the driver's side headlight locate the red wire with silver bands around it, if you have a 12V electrical tester check that this wire is positive when the headlights are on and it then peculiarly goes to negative when highbeam is on. Clip a Scotchblock onto this wire with a piece of wire in it long enough to reach back to where you are going to locate the relay, and attach this wire to terminal number 85. This will be the "trigger" for the relay, the relay will always have a positive feed to the normal trigger, and live going to the "switch" of the relay for the auxiliary spots, so the relay will click closed only when the earth terminal gets a negative feed (as it will normally be positive... "d'oh! my head hurts Marge!").

Take a wire off the battery's live terminal and with an inline fuse holder connect it to terminals 86 and 87, these are the normal trigger and the input terminal of the relays switch.

Connect a wire from terminal 30 - the switched output of the relay - and connect this to the positive wire of your spotlights, the spotlights should also be earthed to either the vehicles body or chassis, or an existing earth point (probably the best idea I've found).

Hmm, and that's it... when you put your headlights on the wire coming from the Scothchblock attached to the red wire with silver bands will be positive, so the relay will not click closed. However when you "flash" your headlights or switch to mainbeam, that red wire with the silver bands will drop from positive to negative, then, as the relay now has an earth it will click closed and switch the positive feed to the spotlights on... and your spots will come on so you can flash other roadusers, or when you're offroad in the dark, etc...

Ok?

Ok?

i was sick for the week so i only did the spotties yesterday, and it didnt work the 1st time around . i knew that the high beam wire goes negative when the high beam goes on but forgot how a convention relay works: it needs a positve power input to the 86 & 30 terminals to get a positive power output to the 87 terminals, and this cant work conventionaly in suzukis.
so i repluged it how u said and 2nd time around it worked .
i know it worked but the only thing i didnt get was how there wasnt an earth. im guessing it doesnt really need an earth for the relay to work?
thanks heaps 4 that post btw

the spotlights need an earth so does the relay , I would suggest soldering the wires scotch locks will corrode the wiring , and you need the hi beam positive for the relay to work. I would suggest a relay too ,

yeah the spotties r earthed, they have 2 be to work! and yeah there is a relay there, read the last post! and no that wont work coz the high beam is positive when the lights r off. thats how suzukis come out. when the high beam in on, the wire is not positive, so relay cant be hooked up convntally. it works the way want33s said.


i just thought the relay had to be earthed but it doesnt seem 2 be, thats all.

noelb1: Your way won't work, but if you reckon it will, Please provide a diagram after you have tested it on your Sierra/Drover.
