most head units have a wire on there plug for power antennas, so as long as you hook the plug up right you should be alright! Good luck!

I put an aftermarket system in my intrigue, and don't recall a "stereo accessory wire". Do you mean the power antenna wire? Or is this a wire on your aftermarket box? Here's a GM diagram: http://www.installdr.com/Harnesses/GM-Wiring.pdf

no. first check fuses. check ground. check for voltage to memory, and switched power to radio. the only time the antenna would affect the radio in that manner is if the ground was connected to the antenna.

check the fuse to make sure it's good and if it is your probably better off buying an aftermarket power antenna for it or go with a regular antenna.

The GMC stereo has amplified rear door speakers. When wiring up the aftermarket stereo, connect the blue wire on a GM aftermarket harness to acc power and the speakers will work. I did the same thing for mine about 5 years ago. Good Luck...

This is only used if your vehicle has a motorized antenna that pops up only when the radio is on, then retracts when the radio is off. A voltage is sent from the stereo through this wire to a relay which applied power to the antenna. If you don't need it the wire from the stereo should be capped off to prevent a short occurring if it were to ground out under the dash somehow.

The antenna relay is on the power antenna itself(in the trunk.) a wire goes from the radio harness to tell the antenna there is power to the stereo and then the antenna goes up when it gets that signal(just by the 12volts going to the relay.)

you don't.. can't replace mast.. the best thing to do is buy an aftermarket/universal power antenna or go hunt for a working one at your local junkyards.

Yes but I'm not sure the benefits of doing so would ever be worth the hassles you'd encounter getting into the very small spaces that the drive motor has to be mounted and if you have an aftermarket stereo in the jeep you'll have to figure out the wiring. Most people want to replace a defective power antenna with a plain one.

Installing a CB radio in a Chevy Impala begins which installing the mount and location a suitable power source. The radio is then mounted to the dash, wired up, and the antenna connected.

First Your Gonna Remove The Dash Trim Molding, Than Remove I Belive Its 3 Screws (One Is Hidden Under The Stereo Itself) From The Stereo Bracket, Pull Out The Stereo, Unclip The Power Dissconnect, And Unplug The Antenna. If You Wanna Reuse The Bracket There Are A Few Screws Holding The Bracket To The Stereo. If You Are Gonna Install An Aftermarket Stereo, Youll Need To Go Buy A Stereo Mounting Kit At Where You Buy The Unit. You'll Also Need To Buy An Antenna Extension. If You Dont Want To Spend The Extra Cash To Get The Adapter For The Power/Speaker Wiring, You Can Go To The12voltdc.com And You Can Find A Wiring Diagram For The Speakers, And The Power Wires. Pretty Much Install Is The Same As Reverse. If Ya Need Any More Help, Email Me At ss101504@yahoo.com.

Some headunits share a power antenna & remote wire are the same wire. If it is hooked up to power antenna and not hooked up to factory amp there is no signal to tell amp to power up

There are a lot of aftermarket antenna masts that you can get to fit your 4 runner and if you do decide to go with a fixed mast just make sure that you make sure that the wiring harness at the mast doesn't ground out on any metal. Other than that there is no problem with replacing it with a fixed mast antenna.

If it is an aftermarket stereo then i would say that the installer tied into the dashboard illumination or headlight power wire for 12 volt power for the stereo.

The motor that raises and lowers the antenna is controlled by a wire which is connected to the power switch in the stock radio. The wire from the antenna itself has nothing to do with raising and lowering the antenna. Touch the wires that were connected to the stock radio to a hot wire and see if the antenna starts to move. If if does, hook that wire to the wire from the new radio which is supposed to control the antenna motor. If there is no such wire, connect the antenna motor wire to the Accessory circut. The antenna will go up whenever the key is turned on. Or, you can get fancy and install a switch for it.

check your fuses i believe they are on both sides of the dash and under the hood. if it is an aftermarket radio check to see if you are getting accessory power

on the 2006 models of the ford fusion. the radio antenna is embedded in the back glass with the rear defrosters. It's important to know that when installing aftermarket radio you should connect pin 5 on the radio harness to a switched 12v source. If not done this will cause problems with radio reception! pin 5 is the antenna's booster power wire and was originally powered off of the stock radio but the aftermarket radios do no supply this power source. I reccommend using a relay and the remote antenna wire and 12v constant wires off the new radio harness to make this connection! this will allow the the remote wire to switch the relay on and off when the radio powers on, and connect the the tapped 12v constant wire to the antenna booster power! thats how i would do it!

You can, but it's quite difficult. The "head unit" in the car is actually mostly a shell, with the tape, CD and display/control units only. The radio module itself is attached to the power antenna in the trunk, and there are amps in various places in the car as well. To put in an aftermarket system, you'll have to build extension cords for the connectors that plug into the module in the trunk to meet the outputs of the new stereo, and a long add-on cord to reach the antenna signal to the dash, too. Difficult, but not impossible.

if it's an aftermarket CD player look for a blue wire with a yellow stripe. if it's stock you need to find the power antenna wire. most decks have 1 even if you don't have a power antenna.

You would need to get a tool to remove the notched chrome piece that holds the antenna mast, or carefully use pliers to unscrew it out. After you remove that, the antenna itself is held by a 10mm bolt. to get to it you'll need to open up the trunk lining near the antenna location and remove that bolt. Then, pull the antenna far enough to disconnect the antenna wire and power. Assuming the antenna motor is still functional, you can then replace the antenna mast with a new one. Or, you can install an aftermarket rubber antenna.

Remove the wiring harness from the bottom of your 1987 Buick Regal power antenna. Remove the power antenna retaining nuts. The power antenna will come off. Reverse the process to install the new power antenna.

squeeze it a little bit with a pair of pliers until it fits snugly in the socket.

Check that the antenna is plugged in on both ends. For the back end, open the trunk and detach the fuzzy trunk liner from the left wall of the trunk (where the antenna goes into the car). You'll find the antenna motor assembly there; you can't miss it. There are two connections on it, one for power (I assume) and the other for the signal. Check that the proper plugs are plugged in and secure. For the front end, you want to make sure that the antenna is plugged into the stereo. If you still have the factory stereo installed, press the two vertical slits on the both sides of the stereo, so that spring-loaded finger holds pop out, then use those holds to pull the stereo out. Ensure that the antenna is plugged into the back. It's a lone, black cable with a metal plug on the end. If all of that checks out, you may need to consider replacing the antenna motor assembly (I got one from a junk yard for cheap) or the car stereo.
