    Post Wire splicing...

    Here's one for the electrically/electronicly gifted...

    I have the 12V. line run from the trunk of my care to the dash, completely invisible. I am now pondering where to hook it up. I don't want to run it all the way to the battery if I can avoid it. I was wondering if I can splice it into the cigarette lighter and still be able to use the cigarette lighter for other devices like cell phone or PDA? Also my FM modulator needs 12V...can I splice it in too?

    Thanks.

    Yeah, you can splice into it. But the question is how much current are you going to draw through that line? You may end up blowing the fuse, but if you dont then your all set.

    It also depends on what size fuse you have on your power inverter. You don't want a 10A fuse on one end and a 30A fuse on the inverter. I tried to wire my PC to my cigarette lighter, but it didn't work. I'd keep burning out the 10A fuse, so I ran it directly to the batttery with a 30A fuse (because my inverter has a 30A fuse) and it works perfectly. The only thing I could get to run off of the cigarette lighter is my LCD. If you want to keep your cigarette lighter, your best option is to connect straight to the battery.

    Hey guys

    Well go all the way to the battery if you can find +12v (constant) under the dauch near your ignition key. Color differs on model of the car but you need to look for a thick wire which has constant 12v in it regardless is the ignition key is on or off. To find this wire use a test lamp or even multi-meter.
    around that area you all so can find 12v ignition, 12v accesories and any other controled power source you need.

    Ok...thanks guys...

    I'll try the modulator first and then add the computer. No inverter for me Gutter... straight DC-DC all the way. I tried it out...it works great. My cigarette lighter is not on the accessory line...it is always on, so I'll try to splice off it first. If I end up drawing too much power, I'll look for that other line by the steering wheel Fosgate. My computer draws less than 2.5 A at 16V, and I'm sure the modulator draws less than that, so I hope it won't be a problem. Thanks for the tip, mate.

    I wired everything up and everything has enough power off that line. My problem now is that my FM modulator from PartsExpress is fuzzing and whining, partly with the engine and partly just backround noise. With a tape adapter it works great, so it is definitely the modulator. I'm going to try to ground it various different places in the car...unless any of you guys have a different idea.....
