DIY:Valenti 3rd/4th Brake Light Mod-Separate Brake light Triangle-2 Options -Video
 

So, there seems to be a lot of threads/questions about how to wire the Valenti 3rd/4th brake light and modify it to work/flash differently. There are wires/cutting/moving/combining/arrows all over etc-I've done this mod before and I was confused by the differences in pictures (upside down/jumper wires all over/new wires added).

When done correctly, there wont be CEL, weird dimming or any other bizarre electrical issues.

There are 3 Main ways of having the Valenti Rear wired

1. Stock out of box-When you turn on the running lights, the "V" AND the center triangle light up. When you step on the brakes, the center triangle flashes 3 times and then remains on. This is less than ideal I suppose, since most of us only want the center part to light up when you step on the brakes-which brings us to the mods we can do!

2. (flashing) When you turn on the running lights, only the "V" will light up. When you step on the brakes, the center light will flash 3 times, and remain on-as long as you step on the brakes. When you release the brakes, the center light will turn off.

3. (Not flashing)When you turn on the running lights, only the "V" will light up. When you step on the brakes however, the center light will turn on-and will remain on until you release the brakes.

The video here shows the different methods AND how the wiring should be setup.
I will have another video shortly that shows which wires to tap into on the tail light side/reverse side-but that content is out there...wasn't a top priority for me. Picture is below

How the wiring looks OUT OF THE BOX. Before modifying.

HAD TO UPDATE-WILL ADD NEW PHOTOS HERE SOON

I'll need to check to see how "plug and play" the harness is on the 4th brake light, might just have to pull/tap the red/blue wire into the tail light.

Where was this 2 years ago before I paid someone to mod mine?! Lol jk, thanks for finally posting a DIY on this! :thumbup:

sick, i was finally going to try this over the weekend based on another thread..

let me know if you have any questions on any of this, I tried to make it simple.

The other threads did okay, but it seemed overly complicated in some of them? I don't know lol.

This is the way i wired up for my V and flasher brake

http://www.modbargains.com/images/FR...trobe-1080.jpg

I use a Jumper cable between the black and orange to connect the stop and fog solder point.

I think is essentially the same as your wiring.

But with the way im connected there were interference with some of the electrical system in the car.

on the BRZ..

If you wire it up like how it is in my image.

The moment you step on brake.(well at least on my car)
The boomerang light and side marker will turn on. Also at the same time The clock display go blank.. and the air bag and driver seat sing on the right hand side of the clock will dim.

When you release the brake,
Clock display come back and other light not dimmed.
Boomerang light and side marker goes off.


Another member has notice the same problem, and here are his solution to it.

I didnt get the chance to take it off to try it out yet.



Just want to see if the way your wire up with the Orange and black wire going to Stop and Fog solder point having the same issues as me by using a jumper to bridge it.

Cheers

hmm, I need a brz for testing lol

and, for reference, the jumper method and my method are essentially the same.

The method in question is this?! I BELIEVE this makes sense. Otherwise, whats happening is you set on the brakes with no running/parking lights on and power goes BACK through the system and essentially powers the running/parking lights.

I will need to test and report back, but this does seem to be correct.

Example below:

Remove the green wire from the solder joint(yellow arrow), and attach the red wire to the green wire(light blue arrows).

@j_motion I was wrong!(about the original video/wiring)

I believe removing the green wire from the board and having the red wire connect directly to it is the way to go.

BUT, I will check tomorrow and update the video!

sounds good

thats what mchasteen1 did on his FRS to fix the interference problem

re-shot the video, will have it uploaded tonight perhaps!

okay, new video up with PROPER way to wire!

From now on this will be the new brainer's post to the valenti's install

Just to be clear, is this for the bottom light that FT86 SpeedFactory sells, or is it the legit Valenti light? Or does that even matter?

This is for Valenti lights...so it shouldn't matter as long as its a "valenti" light.
