For those that have installed one before I could use assistance. I have the light, the switch and the "timer" box with harnesses. Installing in an 85' BRAT.

 

Couldn't find any clear instructions.

 

Thanks in advance

i too am curious. i have a 3rd eye light for my brat and will need to figure it out when the time comes.

Someone may have clearer instructions,  (such as http://www.ultimatesubaru.org/forum/topic/83314-wiring-diagram-for-passing-light-3rd-eye-how-is-it-done/)

 

but you need a always-on hot for supplying the relay circuit, and switched power for the lamp switch. This way when you turn the car off the light goes off and the door closes. Or you can wire it to stay on without the key, just run the switch to hot, and hope the battery stays good if you forget. I wired it to key switch because I forget.

 

 

 

Main tricky parts

is cutting out the welded radiator support, at the front. not to worry, that lamp bracket is more substantial than what you're removing. I removed just enough, and then part two: 

Cutting the newer grille (in my case) to fit the cyclops door. You'll have to get everything locked down grille-wise to make sure the door clears the grille smoothly.

 

Interior: Drill out blank circle. May be easier to remove and drill, but otherwise, put the hole in, put the switch in behind it...

 

Be careful, one car I pulled wires from seemed to have had damage from a failed lamp switch. It breaks apart, leaving all those nice bare leads right in the middle of metal brackets.  I gave mine a wrap in electrical tape just to be sure.

 

 

Also, there's a couple of levels of bulb brightness you can get. I went for the lower wattage because I have 4 other headlamps and was concerned about heat.

 

 

 

I got the grill and radiator support covered... it's the electrical that is definitely the challenge.  Question for you... where does the Red (blue) wire from the switch and the Red (green) from the timer/box go too?  I didn't see them on the diagram you linked to.

 

Thanks for your help,

Anyone...

Pm mcbrat who is now vaportrail on here. In a thread I was reading said he did it but there was no diagram or anything helpful to wire it.

Anyone...

I know this is a old thread but did you ever get the third light sorted out?

If so where did you end up hooking the wires from the switch to?

In the last post, Gloyale has some diagrams:
