Fuse box selection for horn

Fixed

 

Bump someone has got to know this! It's probably the same spot where you would wire a CB/PA.

 

You can tap into one of the wires at the ignition harness. There will be a few thicker wires coming from your key cylinder. Tap into either black/red, blue/yellow or blue/red. Any of them will work, they should be about a 12-14 awg wire.

 

Do you have a multi meter? Just find any of them that has 12 v with the ignition on.

 

Ya I don't have a muti meter. Let me see if I can upload a pic of the options later. Not too crazy about the cig lighter, because if I forget to turn it off. I don't want a dead battery

 

Your cig lighter is on accessory power, when you turn the truck off it shuts off as well...can't drain the battery

 

all right so I went to autozone to get some help and the guy was not much help. He tried to tell me to get some stereo guy install it. Even for me this doesn't seem that hard. I ended up buying the cig lighter adapter at radioshack. Hoping for the best

 

Problems. Connected negative to ground, under a bolt. Connected the positive to cig adapter, note there is a positive and negative terminal on the adapter. The negative is empty. Help! The pa will not turn on

 

I'm not sure I understand what you did. you bought an extra cig adapter for the pa system? What is the hot wire hooked up to? pictures would help.

 

I'll get some pics up soon. The pa system and horn is one unit meaning they both run off one power source ( +12v). Instructions say to ground the negative wire and hook up the positive to a 12 v source , the hot wire. I was not able to hook the positive wire in the fuse box so I bought an adapter for the cigarette lighter. The adapter has a postive and negative terminal. The pa system will only power on if the negative ground wire and positive are both wired to the cig adapter. I guess my question now is how do I ground it when the intended ground wire has to be plugged into the adapter. Thanks for the help

 

Any ground will work. You can either wire it to the cig adapter that you bought or you can ground it straight to a piece of the frame. If it works with the cig adapter I would just ground it there, and fuse the hot wire. I would like to help more but I'm still a little confused about what you bought from radio shack and how you have it wired.
