Will I need anything else to complete installation?

Whats up guys, glad to be here! Awesome site...

So I'm about to order my stuff from Oznium to start my first lighting installation. I've been doing a lot of research on the website and have got my plan lined out. I plan on running 4 pre-wired LED's in my vents, set of cathodes under dash on driver and passenger side, and another set of cathodes for the back seats. I just wanted to double check with you guys and make sure I'm not forgetting everything, this is what I plan on purchasing as of now:

(1) Illuminated Toggle Switch
18 gauge wire (red and black)
(4) Red PreWired LEDs
(1) Blue Catode Kit
(1) Green Cathode Kit

I've got a couple of questions for you guys...

Can I run all of this to my single switch?
As I'm purchasing the prewired LEDs, is it still a good idea to get an inline fuse/fuses?

If I'm forgetting anything, just let me know! Thanks guys!

If you're going to tap into an existing power source then you don't need a fuse. If you're going to run a new power wire from the battery then you DO need a fuse.

Yes you can run everything to one switch.

Awesome, thanks a lot!

Also, will I be able to run the 4 LED's and the cathodes in Series with eachother? Thats the general idea correct?

Since they are pre-wired, run everything in parallel.

might get 2 more transformers or you can only spread the lights like 2 feet from eachother.

Running in parallel, I won't need to ground every LED/Cathode seperatly will I? There's gotta be an easier way right?

Also, I'm running the first set of cathodes up front, and the second set in the back, so the pairs themselves won't be too far apart from eachother. Do I need a couple of more transformers to wire the front cathodes to the back ones? Is that necessary or can I do it another way?

To ground your stuff, just run a negative wire alongside the positive wire and ground that wire somewhere. You don't have to make individual grounds for everything. I used a bolt that goes into the steering wheel column to ground my stuff, and my setup is identical to what you're planning.

I got extra transformers, it makes it a lot easier not being restricted by the short white wires.

Thanks guys. I was looking at the diagrams and wiring scheme's on here and I guess I got confused, as it looked like in parallel every light source had to be grounded individually...but I understand now.

Is there any specific order I need to wire up the LED's in conjunction with the cathodes?

Ray, there's no order at all. Run your red power wire from wherever you're getting your power (making sure its fused somewhere), and split it off to go in the directions you need it to. Hook up the LEDs and cathodes to the red wire, and to a ground wire run along the same paths as the power. It really is that simple

Haha aight man thanks a lot for the help. Just needed to clarify some things before I started chopping up wires;)

Every light source does have to be grounded, but there are many ways to do this. One way is to run the negative of each device to its own ground (sounds like you don't want to do this). Another way is to run the negatives of each device together and then connect that to a single wire, which will be grounded. Somehow, you need the negatives of each device to go to a wire that goes to ground. You can wire multiple ground wires together to make one if you like and that's acceptable.

Not a problem. Let us know if we can help further!
