Connector Info

[OtakuDJR]

I got the new GT-R, and this is my first xmod.

I'm looking to add lights, and I assumed that the connectors (in the attached picture) are used for such add-ons.

Does anyone have details on what each pin does? All four pins can't be power.


My plan is to get LED lights for the headlights and brake lights, using button cells (watch batteries) mounted to the body kit, but if the pins send current to indicate anything about the car (for example, if the car is moving or stopped) then I could use that info to make brake lights that dim or brighten to match.

Also, does anyone have information as to what degree weight effects xmod performance. (If adding some button cells, resistors, wires etc, is worse than just drawing power from the chassis, might as well do that)

Thanks in advanced

They are for the light kit and the neon lights underneath

does anyone know what the pins do exactly? or does everyone just use the circuit boards that come with the light kits?

I've read of aftermarket parts that light up brake lights when you stop, do standard light kits do anything like that?

if I'm asking horribly noob questions, I'm sorry :P

Yes, the headlights light up when you accelerate, and the tailights light up when you slow down.

On the four pins, the one farthest to the right is negative, and the one to the left of that is positive.

Does anyone know what kind of 'data' the other two pins give out?
Or should I just experiment :P


I basically want the headlights to stay on all the time, but brake lights to brighten when slowing down.

You could probably modify the circuit board for the light kit to do that.

2 pins are control power, 2 are signal for brightening the lights when you brake or go forward.
with what you are wanting it will be better just to get the command logic lights, (xmod light kit), and do the constant head light mod. saves you time, money and headaches.

but then I'll be buying an xmod light kit :P
I want to try and do things hand built as much as possible.

The CLL board might depend on power from the connector to the board. (Which wouldn't work if I use an external power source, ie. watch battery)
I just was going to build a simple circuit that would brighten/turn on the brake lights when slowing down.

I was just wondering how much detail people knew on the 'data' from the connector. If they simply send signals for going forward/back then thats not much to play with. But if they sent signals for turns, how fast, etc. That could be alot more fun

can someone post up a thing for the constant headlight mod?
