R33 GTST Tail Light Wiring...

[GiJOr33]

Hi Guys,

Just wondering how the tail lights are wired up. In the picture i've attached i've drawn the ways i think it might be wired.

The first set has the power for all four of the tail lights all daisy chained from one power location for each of the filaments and all sharing the same earth

The second set has each pair daisy chained to together but then going to the power location separately to the other pair.

I understand they both get power ultimately from the same source, either the brake switch or the tail/headlight switch.

I'm working on a little electrical project and what i'd like to do is be able to cut the power to the two inside lights of each pair. I tried this by cutting the earth for the two center lights but what happens is the tail lights still come on, when i press the brake light this also lights up the tail light filament. If the tail lights are turned on and i press the brake then the filament goes off. The brake filament doesn't light up at all.

I'd like to be able to enable or disable the center tail lights and leave the outside ones working only. What i was thinking of doing was cutting the power to the tail light filament and the brake filament individually and putting a switch in. The only problem is i will need 4 switches. Two for the tail light filament and two for the brake light filament. Ideally 1 switch would be good but will probably have to go with 2 switches. Maybe i could daisy chain the two tail light wires together and the two brake light wires together and then put one switch in each of their power lines... i dunno

Hopefully someone can understand what i'm crapping on about... so if ya can, shed some ideas! Or if you have the wiring diagram of the tail lights that would be even better as i could then see the entire path of where the wires go and decide on a point of interception

Thanks

The pic looks like a daisy chain.

yeah they are just two ideas that i came up with for the possible wiring. I'm kind of after confirmation as to which one it is and ideas on doing what i'm after.

A daisy chain is where one globe is linked to the next and the next but not in series... still a parallel circuit. Just means you don't have to run 4 separate wires, you can just run one bigger wire and splice into it for each globe filament

Cheers,

From what i can understand you would need to do this with both the light swith and the brake... if it was wired that way (i'm not sure). So you would definitely need 2 switches with this system... i get the feeling tho that all the lights are wired up in parrallel which means you could need 4 switches

oh its a circle of guys bum fcukin LOL

sorry for the Off Topic

Why do you want to do this for GiJOr33

Are you doing this to give your R33 the Series III GT-R look possibly?

my tail lights already only light up just the outside ones... have done so since i bought the car 2 years ago. I'm not 100% sure if it's legal so just wanted to see if there was a way i could turn them back on easily if need be. I presume it would be legal as there is a fully functioning set of tail lights and brake lights, but i'm not sure if the lights from the factory must all be lit up as designed.

I think i might just have to daisy chain the two inside ones together and then put the switches in there... all sounds like too much effort though and i'll probably end up leaving it the way it is!
