I think i already know the answer to this, but i thought i would throw it out there anyways. I am trying to hook up cd player in my camaro, but i cant get the wiring quite right. I cant find a good splice for the auxillary wire, (the red one), and was wondering if it would really be that horrible to just splice it into the main power wire into the deck (the yellow one). It is purely a short term fix i need, for the next day till i have the time to do it right.
any help would be great

 

it will work fine, you can use your radio w/o the car turned on. Just don't leave it on and kill your battery.

 

why don't you use a 12v test light onthe fuse box find one that doesn't work with car off but works with it on , I belive something around 15amps should be good for head unit. just make sure it's not part of the head light or turn signals.

 

for about the same money you spend on a test light, you can get a cheap multimeter. Much more useful.

 

either one will works , if he has a test light then he could use that , like so with the multimeter he he can't afford either if he doesn't have one , all you need is a couple lengths of wire some E-tape and a 12v light bulb

 

while he's putting the tape around that bulb, I can run to harbor frieght tools and pick up a fully functional multimeter for $2.99 and measure DC,AC,amps and ohms.

For $30 you can get a decent crafstmen multimeter, it even has a capacitance checker on it.

The funny thing is I've compared it to a $400 fluke meter and it's dead accurate, except for some very precise resistance readings...which were still only off by .002 ohms

The $2.99 meter (yes I bought myself one) works ok too, It checks voltages accurate enough for most any electrical system work.

 

or he could just plug a male spade terminal into one of the three plug ins on the fuse block labeled "ACC" and run it to his deck and be done.

Test light... multimeter... who cares, try reading the farkin' fuse block.
