Q:I just installed a backup camera however I am having trouble wiring it. I've read that I need to tap into the reverse wire, however I went through many wires and couldn't figure out which one is it. My cameras wire is designed to be wired in the trunk, so the wire under the hood or dash is not a possibility. 2003 G35 Sedan

You can remove your tail light and tap into the reverse wire there. It is easy to find just look at your reverse light bulb and use a multimeter to test for positive and negative (that would be the right way to do it at least). If your wanting to have the camera able to be on all the time and viewed from the headunit then you would need to wire the camera to switched accessory so it has power when the car is on and hook up your head units wiring (which you will need to do anyway to make the h/u switch to b/u cam when you go into reverse) to the reverse wire.

Q:What is wire Harnesses?

A wire harnes is a set of wires that has all the conductors needed and can just be installed into something. There's a wiring harness in your car. They don't install the wires one-by-one. A harness is built for the product and is installed like any other part. There can be many branches on a wiring harnes to go to different places in the product. There may be more than one harness. There could be one for power, one for communications, etc. This is more efficient than installing separate wires.

Q:(For my PC)I want to have a quadrophonic speakers (4 channels), but i want to extend 2 speakers, but their wires are limited and cant extend enough to reach my rear? what should i do?is it as simple as, cut the speaker wires and extend it with a common copper wire that you mostly found on most appliance you found on your home?

Yea ive tried extending and cutting the coper wires, this situation has its faults if you decide to do it this way so id suggest just grabbing another at a local shop or OKorder.

Q:Suppose we have a 10v battery.one end of the battery is at 10V electric potential and other is at 0V Hence,the potential difference is 10V.if we measure the voltage( p.d.) across positive terminal at 10V and the middle of the wire connecting both ends of battery will it be less??I mean,at the middle of the wire the electric will not be zero,right??(correct me if am wrong)Thanks!!

If the wire had some reasonable resistance which prevented melting of the wire and explosion of the battery; the middle of the wire would show half the potential difference between the terminals. The wire connecting the terminals becomes a potentiometer with Voltage falling linearly between the terminals (assuming uniform resistance along the length of the wire). In practice, Voltage drop on a wire supplying power to a load is proportional to the resistance of the wire divided by the resistance of the load. When the wire is the load, all Voltage drop occurs along the wire.

Q:trying to find the radio wiring diagram for my suburban to find out where all my speaker wires are .

Q:I just bought a remote starter/keyless entry/alarm system, i'm looking to install it myself... I'm just wondering what gauge wire that most cars use.I'm assuming power wires are lower gauge then others, Could I use 16 gauge for power lines or would i need something larger?Thanks in advanced.

i use 16 gauge wire for my car alarm and stereo and ive had no problems so far.

Q:I just bought an aftermarket cd player for my Grand Cherokee and I would rather not have to cut and strip wires so I want to get an wiring harness adapter. My question is, can I just get any wiring harness adapter or do I need the direct connection adapter that is specifically made for Chrysler to Kenwood?

You just get the jeep wiring adapter and then solder or use crimp caps/butt-connectors to connect the wires to the aftermarket harness that comes with the aftermarket headunit. Also, depending on what year Jeep you have you may need an antenna adapter. AND I believe on the Jeeps (like the chryslers) there is not a usable ground wire in the factory wiring harness which means you will need to ground the aftermarket ground wire to the chassis via an existing bolt or drilling. Or, if the stock radio has one of these metal-mesh things affixed to the back, you can use that thing as well. But when you match up the Jeep harness you buy to the factory harness and you will be able to tell if there is ground wire in factory harness.

Q:i have a 00 gmc yukon and tried installing my cd deck. i pulled off the original harness from the stock deck radio and now its just all wires (its my first so i didnt know), i connect the alpine deck wires and tried to connect them all together. i had a few figure out, except a small noise coming from my stock tweeters every time i step on the pedal. then my speed odometer sensor was going with the bass of my subs... whats wrong? can someone find me a chart of what color wires supposed to go where? thanks for your help

I think you are just better off doing a factory amp bypass and there shuld be a harness you can buy that will hook from the wire behind the factory amp to your deck.

Q:I wired up my brothers stereo in his 1994 volvo 850. At the time, I knew nothing about wiring harnesses so I did everything one wire at a time. I got it working but the stereo can still run with the car off. If you turn the radio off, a small led stays lit on the front. My brother couldn't get his car to start this morning. Could this little light be drawing enough power to run the battery dead over night? Should he just get a wiring harness and hook wires up like that?

If the stereo runs even with the ignition turned off, then you have wired a continuous power supply to the radio instead of an accessory, and that will drain his battery. I always recommend using a wiring harness when installing an aftermarket stereo, as there is no way you can accidentally wire something wrong.
