Hi all,
Just de-bodgifying some stuff the Japanese owner left on the SE, one issue of which was a birds nest of bullet connectors and scotch locks on the stereo.
So I'm fitting a standard ISO connector for my stereo using the colour guides - simple enough stuff. However my stereo doesn't have a pin-out for the power antenna. On a previous car I just wired the ACC wire direct to the power antenna so it always raised, however on the mk1 it raises the antenna but doesn't lower when I turn the car off. I guess it's a different system on the mk1? Any guidance please? I'm probably one of the few who kinda likes the old-school power antenna, so would like to retain it. Not sure if it's related or not, but for whatever reason the fella had wired in a separate earth for the stereo (connected on a ring connector to the cage), rather than use the standard brown wire - could that be related?
Cheers,
Jon

Re: Stereo wiring / power antenna
If you still have the original MK1 aerial with the blue relay in the boot then it needs a signal for up AND a signal for down, unlike most electrical aerials that go up with a signal and go down when the signal is removed.
IIRC Pink/Blue wire is the up signal and Black/Red wire (at the harness behind the stereo) is down.
I seem to remember if you join the two wires together and connect to the ACC it will go up and down with the ignition, but I may not be remembering correctly

Re: Stereo wiring / power antenna
Amazing help, thanks Jimi, that would back up my experience with it so far, so I'll give that a try! What do you think ground-wise, use the factory brown, or give it a separate one on the cage? Nowt to do with the antenna, just trying to do the 'right' thing for the car.
While I have you, I don't suppose you know the what wire colour is what on the factory UK rear fog switch? I've sourced a switch with pigtails to convert the o/s reverse light.
Cheers,
Jon

Re: Stereo wiring / power antenna
The factory ground should be fine, works OK on mine.
Fog light is Red/Green from the the switch to the light, Red/White from the fog light relay to the switch (fog light relay is only energised when the light switch is in the headlight position)

Re: Stereo wiring / power antenna
Thanks, just to confirm for anyone coming across this thread later, what you said worked bob on for the aerial, though I think it might black/red up and pink/blue down....not that it makes much difference of course. Might add a switch at a later date but for now at least the audio is tidied up, 100% working, and 'safe'.
The headlights are doing a dance on going down, I've tried two retract control relay boxes and it does appear to be better for a time with a little WD, but does return to the dancing. Reckon the 2nd one I bought might have been duff too, anyone got a known-good one for not too much dollar?

I am pretty sure I have a spare relay box, let me have a look and let you know. Would only want postage.
I am going to live forever, or die trying!
Re: Stereo wiring / power antenna
Cheers, I've had a look in both the control boxes and can't see anything obviously wrong - dry, and nothing burned/domed etc. I did see a youtube comment from someone suggesting that it's a particular solder joint that goes dry and comes away from the board, so I guess I could have another look at that.
Someone else said that the Celica ST162 box is the same too, and my other classic project happens to be a ST162 with headlights behaving properly - so I'll try swapping that in after I get home from work.

Indeed
1987/89 Celica ST16# and 1987/89 Corolla AE92 both use the same Retract Control relay as the MK1
Might be worth trying both your relays in your Celica, would prove if they are faulty or not
Re: Stereo wiring / power antenna
Pink/blue wire powers the interior clock, stereo and aerial power, it's a switched live, but I think the aerial lower is powered by the dome light live so it can lower when the car is deactivated.
I fitted a 90's Celica aerial to mine and it fits fine - it has the relay in place, all you do is swap the connector over. It looks standard as well.
