I wanted to install a few cigarette lighters in my old 1996 Toyota Camry that my sister just gave me since it only comes with one, and I want to have a dash cam/parking cam AND to charge my phone, and while I'm at it, add one in the back. I located the fuse box, and will find an accessory fuse that only turns on when the car does, but the box is already full of fuses, no empty spaces for new ones...As soon as my volt meter comes in the mail, I can see which turn on only when the car does, and look what each is for so I don't use something necessary... I know ones for the existing cigarette lighter with a 15A fuse. Here's my dilemma: I want to use one fuse and attach 3 or 4 of the 12 gauge wires to it (I chose 12 so the wires wouldn't be the limiting factor, I'll see the amp rating of my devices so I can put a low enough amp fuse so I don't blow my items I plug in). I'd get a fuse tap, but the wires that come on it look a bit flimsy, and I want to split it 3 or 4 ways. I basically want to know how to split my power 3 or 4 ways. I have enough wires, I have extra fuses that I bought, and 10 inline fuse protectors too (full list below)... But how do I get 3 or 4 wires to connect to the 1 fuse? Do I connect 1 to it, then use a quick splice wire tap that cuts into the protective outer layer of the wire, then put heat shrink on it, then tap that one, then tap the next and the next? How would you go about splitting the current 3 or 4 ways? Is there any other type of wire splitter? Like how we have for coax cables that can split the power? Is the I ordered a few cigarette lighters from eBay some 12 gauge wires black and red 50 foot ones, a 10 pack of 12 gauge inline fuse protectors, yellow butt connectors (for 12 gauge), some ATC fuse taps (some said hot, some didn't) and crimp on female parts that attach the 12G wires to them. some crimp connectors that would attach my 12G wires to the cigarette lighter, heat shrink tubing (0.5mm) wire protectors an assortment of ATC fuses (standard size, not mini). Solder, a soldering iron, wire cutters that come with the crimping ability and stripping ability. A volt meter. I have a drill, which I'll find before the items get here, but I'm sure I'll need to buy bigger bits for it, or maybe use the ones I have and just extend the hole. Right now, the car needs some work, and the plastic is missing from under the steering wheel, it needs new door handles, both power windows on the passenger side don't work (maybe a blown fuse or loose/faulty wire), may need a new ignition cylinder, and the wires are already exposed, so I figured I'd get this done before my mom and her boyfriend go to get the pieces for it and get them attached and fixed up. To be honest, I've never done this before, but I did a hefty bit of online researching, and YouTube video watching, and found all the parts I'd need, and went through it in my head how I'd do it many times, but just never saw anyone doing more than 1 cigarette lighter install...and I'm trying not to tie up too many fuses since the guy my mom used to install her viper will need some for the viper he's going to install in mine...after it's fixed up.
