So ok, I have an aftermarket stereo, and the stock original power antenna (88 T2) apparently with the ground trigger. I read the FAQ's and it mentions wiring in a relay that looks "like this" but the picture is a dead link for me. Anyone know how to do this or able to show me another thread that explains it. Yes I searched for the last couple of hours but I cant seem to find the actual write up on how to do it.

Any help is appreciated.

 

Here's the pic from the dead link.

 

So, how would you obtain a relay like that, or do you have to build it?

 

Radio Shack has them.

 

I've got an extra relay that you can have...if you pay shipping on it. Send me an PM if your interested.

 

thanks thats perfect

 

PM sent!

 

It's a standard automotive relay available from any auto parts or electronics store.

 

I'm somewhat confused by the diagram. What do the numbers (30 85,86, 87) relate to? (I'll probably feel like an idiot when someone tells me, but I'm no electrician!)

 

how could you stop the power antenna from going when you turn on the radio? i think the fuse for it also does the stereo so that's no good to pull.

 

Those are numbers that are written on the relay itself for each of the connections. Advance Autoparts has a relay for $4 that you can use and I believe that Radioshack has them for $7. Just make sure it is a 12 volt relay.

 

Click, read and learn.

Also, something to keep in mind is that the stock antenna is in the UP position when the relay signal wire is connected to ground, and when its disconnected, the antenna is down. Most newer stereos put out a 12v signal for the antenna to go up, so you need the relay (or at least a good NPN transistor) to reverse this signal, making the antenna work properly
