Yes I agree mur - I meant that figuratively and have edited thusly.

There is no need to cut any wires. The blue/red and blue/white that normally feed the headlamps are disconnected from the multi bullet connector and connected to the trigger wire that turns the relay on. The relay takes current at the highest possible voltage right from the alternator and battery and routes it along the shortest distance straight to that multi bullet connector. The whole affair can be returned to original in no time if necessary.

I found all this a lot easier with just the basic template instead of a diagram.  You then automatically know what to do with everything and can figure out where you want to stick things for your own setup.

1.  Your headlight positive lead gets cut (figuratively), and a relay inserted in the middle.  That's why there are two power leads on the relay.

2.  The relay's trigger(yellow) and ground are for operating the relay.  Either one can go to a switch.

Period.  

End of story.  

Give this a few days to sink in and you're home free.  

My setup is overkill, I also wanted to add a fuse panel to accomodate an aux fan and Cibie Oscars with 65W bulbs.   Instead of one relay per light I could have done 1 each for headlights and driving lights.   However even a 20A fuse gets hot with the Cibies on, and the relays are warm as well.  

Mike, you've got E-mail

OK got it blown up and saved it. thanks.

what are  the two terminal rectangles above the lamps at lower end of diagram?

Mike, click on the image then right click it to view image then press control + to size it.

John,

can you em it to me from my profile?  I can't make the image large enough to read it.

thanks.

Mike, does this help?  I did this using Mur's switched ground. 

John,

posting it here is fine and will benefit the community. Thanks.

I can do both -

Jeg,

sorry, Yes, I'd think I'd like two dash toggles with indicators.  I've collected lots of fog lamps over the years and have some clear and also yellow glass. I really should put them on a car and enjoy them.

I guess two separate relays.

Wanna post it here, or shoot me an em?

Mike?

i'm pleased to hear that your finally starting to spend your money wisely....

mine is MK3 and im buying a clear lens(upper) for MK4,,, dunno if it fits

In some markets MkIV MINIs got built in reverse lights, .....in some markets MkIV MINIs had the same tailights as MkII/III.....I don't think they interchange unless you change the assembly

ok thanks trolly, hmmmm you're nice afterall... hope you're telling the truth.. lol,,, ok im leaving this thread now

Yes. Now stop derailing threads. This thread is about headlight relay wiring.

just a question about tailights, sorry it's a little off topic... are the tail light LENS of MK3 and MK4 the same size?  ty

Cool - I'm just doing them in Word, so it's difficult to get striped wires.

I'll try to help out. But I got a new computer and all of my custom Microsoft Visio stencils are gone!! Sooo irritating. They were all made from scratch and perfect for automotive wiring diagrams. Trying to build them back up now.
