Cressida owners - how do you wire up the elec antenna?

As the title says,
I just installed a CD player in my '89 mx83 and cannot work out how to get the electric antenna working. there seems to be at least 3 wires from the factory deck that go direct to the antenna. I have tried the trigger wire from my new deck on all of them and nothing seems to work. Some of you others must have aftermarket stereos, how did you get the antenna working?
Any help appreciated

Hello, I'm the dude that wrote that, I did it as part of some doco to install an aftermarket stereo in the cressida. The reason for the strange wiring is unknown to me, If the radio didn't want the antenna up then all it had to do was to lower the voltage of one particular wire. There was one "remote" wire on the antenna, but the head unit seems to wire a few extra wires to control some part of the amplifier unit in the antenna. Unless you have the patience to wire up a relay or two, to me it was cheaper to buy a 30 dollar auto antenna unit. Also you dont blow anything up this way.
Check my website out for the full doco if thats where you got it.
The antenna is the difficult part of doing a stereo in the cressida because of this, if you are desperate to get the factory unit working, go to a stereo installer. They should be able to help you.

It's probably due to the fact that the "radio function" only raises the antenna - so it's not just a "power on" feature. eg, if you power on the radio, the antenna raises, but if you then switch it to CD or Tape, the antenna retracts again..
does that offer any insight as to a way around it ??

I know a bunch of ma61 owners who have the same problem (me included)
toyota just have some weird arse way of doing it.
fortunately it doesn't worry me, as I dont listen to the radio (except now, while my supra is off the road, and my get round car has no cd player)

I had figured it was something to do with the radio being on or etc. I was hoping someone had worked out how to trigger it by earthing or shorting wires etc. I'm going to have a fiddle on the weekend and see what I can come up with. Will let u all know if i work it out. Christ it can't be too hard. I work on Aircraft wiring for a living.
