Re: power antenna wiring

Don't understand what you want from someone. Did you find the correct relay or do you want to wire your own stuff to the antenna?

If you want to get the antenna to work the Dk/Grn is always ground. For down you need to send +12v to the white wire and for up you need to send +12v to the gray wire.

I could draw you a schematic with 2 aftermarket relays if you want.

Re: power antenna wiring

yea soory maybe iwasnt clear on my question, i want to know how to wire it my self with new wires and realy. the way it is rite now wen i apply ground to green and power to grey i believe it goes up but to make it go down the green wire must have power in it and then ground to either gry or white eithter one makes it go down, so i am also wondering maybe there is something wrong with the antenna?

Re: power antenna wiring

woops I read the diagram wrong the first time.

When radio on and acc on Gray is Grounded and Dk Green is 12v

When radio is off Dk green is ground and white is 12v

I can draw you up a diagram for 2 relays sometime but it wont be in the next day or 2 so if you can wait I will do it for ya. Prolly do it in a paint document.

Re: power antenna wiring

Cause they have the relay MADE to do that. The regular Bosch relays are not set up to do all that in one housing. It wouldnt be a huge deal. I could even make the relay pack for you and send it to ya for a small fee. I would make the wires coming out of it same colors as the ones in the diagram. Just let me know and tell me how long of wire you would want and I would do it this weekend prolly then send it out and you could have it by next Wed.

Re: power antenna wiring

Not to be a jerk, but I am not going to do the drawing unless you need it then. If you cant get the other one to work let me know and I will take the time to help you, if you dont NEED it then it will be a real waste of time ya know?

Re: power antenna wiring

well the diagram for the 2 relays would be a HUGE help cuz i dont think i will be able to get the original relay out as i have attempted to before and its in there really good, so if it wouldnt be to much trouble a 2 relay diagram would be a big help if not i ll prolly just spend a couple hrs tryin to pry that bad boy out nd go from there

Re: power antenna wiring

First thing are you sure the antenna works properly?Easiest way to get to the antenna is to take the wheels off and remove the inner fender liner(is you haven't already found this out).You can't locate any of the interior harness?It may be tucked/secured up under the edge of the dash.The antenna harness on my '83 is secured up under the dash.It was disconnected because the antenna stopped working(I've since replaced the antenna).Start with the pink wire off the back of the radio's harness to see if any of the factory harness is there.There could be a similar problem with yours as mine.

Re: power antenna wiring

That's great the antenna works good.On the harness what you may try is going to a salvage yard and looking for mid '80s full and mid size GM vehicles with a power antenna.They use basically the same harness as the Camaro plus they are longer.This way you could rewire yours without adding another relay.

The wiring from the antenna can be rerun back thru the same body grommet the antenna cable runs thru(if you haven't already done this).

Re: power antenna wiring

I have an 88 IROC and am familar with the wiring for the power antenna. The relay that you're referring to is actually very simple to remove, it just appears to be difficult. It appears to have two screws holding it when actually it is hooked to a prong. They're about 20 dollars new or you can use one from any Camaro or Firebird that had a power antenna. The three wires that you are referring to goes to the relay but only two actualy lead from it and only one is then hooked to the car stereo. If you need more help, feel free to email me at Ryas2kidz@aol.com

Re: power antenna wiring

Thanks for this OLD thread, but it helped me a lot !!!
Just i don'd find where is the relay, and what Part Number if mine is dead ?
(actually i don't have 12V post contact working, so my radio is on 12V permanent, and antenna wire not yet connected, so i can't test yet if it's goof or not !)

Like to convert my 90 bird from mast antenna to power antenna. I have the correct antenna for the conversion. The wiring is correct. But I do not have an existing relay in the dash. Also, how do I wire to the radio from the relay?
Any help would be appreciated. If you could help me get this power antenna up an running I certainly would compensate you for it.

Just wanted to point out this wiring is WRONG. If you make Dk/Grn always ground and bench test you will break it because it will always be retracting. See this thread of correct wiring information

If I was trying to do this, I would purchase

Amazon Amazon

You need to drill out the top rivet so you can turn the outer mast 180degrees so it works with the Camaro mount.

Then using the information from the other post you would need to do some wiring. The radio will normally have a power antenna out single 12v positive wire. That will give you the power up while the radio is on. The harder one will be to send the 12v power to bring it back down. I am not sure if that is always supplied and could basically run down the battery. Or if it runs for say a minute or two after the car turns off. I assume that is what that whole controller is doing that everyone talks about where the relays plug into.

FWIW as you can see from the amazon link this is the same antenna used in 88 Jeeps Cherokee. So maybe you can find some wiring help from there.

Even if the information is wrong? This is the top hit on google for wiring on power antenna. I guess we could let the wrong information keep getting spread.

I know this an OLD post but I wanted to ask if this person ever got the answer to what they need. I believe I can help them. But could not find how to contact them privately so here I am trying to get ahold of them. Don't get on my back for trying to help? After all that what forums are for is it not?
