Hi,
I had a Pioneer all singing and dancing DVD, ipod, radio player put in the MR2 today and low and behold the ariel will not stay down unless the whole unit is turned off, I was thinking about fitting a toggle switch so that I can operate the ariel manually when and if I ever listen to the radio, I need to know the colour of the live wire going from the unit that operates the ariel and my plan is just to put a toggle switch somewhere along it's route..I do not want to disable the ariel altogether....
ta for any help
Mike
The black wire from the radio connector is the one that controls the aerial. I'm not sure what the voltage is for up or down, but I'd expect it to be 12V for up and open circuit for down. Best thing would be to measure it with a meter.
I did the manual ariel conversion today using the passenger side window lock switch, easy peasy took about 20 mins the hardest part is getting underneath the dash to secure the wiring, (not a lot of room beneath that steering wheel) the wire for the ariel turned out actually to be blue, now I can drive watching dvds, listening to my ipod and discs without that damn ariel stuck up in the air,,,,,,,,,

I certainly hope you do not do that? s:scared: :scared: s:scared:
oh yes, I constantly watch Braveheart on the road,,, it is a totally historically correct film don't ya know,,,,, s:lol: :lol: s:lol:

I appear to have the opposite happening to me....the aerial won't raise.
Has anyone else come across this?

Can you hear the Aerial motor noise attempting to raise the mast, if not ,I assume there is a seperate fuse that may have blown!

No I can't hear the motor, it doesn't do anything.
It was working fine until I switched my standard double din to my new single din head unit, so I presume it's a wiring issue on the ISO block, rather than aerial failure.
The standard headunit used to dim when I switched my lights on too, but this new headunit needs that wiring up seperately, so I presume it's something with the auto aerial that needs wiring up...but I haven;t a clue how!

Yup same happened when I fitted my pioneer double din. The wiring at the back of the pioneer loom had a wire with a break apart connector on the blue wire. Once that was plugged back in all was good. Some people don't connect it as the ariel is annoying I guess. I think its the same wire used to tell amps to turn on as well. Basically when you turn the HU on this wire goes +12v. The beauty of the MR2 is you can have a look at the wiring without needing to remove the HU as its open at the back s:wink: :wink: s:wink:
Thing that's really foxed me, is when I plugged the ISO wiring harness into the original Toyota wiring loom, all the pins were used/taken up, so the aerial wire must be just hanging around at the back of my headunit somewhere...so where in god's green earth does it attach to? ..and likewise for the "ILL" wire for the side light/dim function?

It's a wiring issue....from memory the aerial wire is blue on most ISO systems, have a look see if you got juice to the blue wire with radio on.
The illumination wire on most systems is orange, just make sure it is (might have it on the wire) before connection to the unit's corresponding wire. Check out the HU manual first.
Hope this helps.

Hi B,
Yeah, the aerial wire is definitely blue and the sidelight wire is definitely orange, because Mr Pioneer very helpfully put little tags on them, but that doesn't answer the question of where they need to be attached/spliced to?
Should the blue/white aerial wire be spliced to the switched feed to the head unit, then I can extend the wiring to run to the passenger window lock button & control the aerial myself?
As for the illumination/orange wire, it runs out of the stereo wiring harness but I don't have the foggiest where it should connect to the toyota wiring harness. I guess this one isn't quite as important to me as the aerial one, but the blue lights of the new head unit are quite bright!! s8) 8) s8)
Hm,
If I'm understanding this correctly, you can indentify the blue aerial wire coming from the HU, your problem in indentifing the aerial wire in the Toyota loom?
I can't remember the aerial wire on the Toyota loom but if your using the ISO connection surely it's blue? Aternatively, follow the blue wire on the ISO lead to confirm which wire it connects to on the loom.
The obvious other way to confirm, is to trace the known wires, the Speaker wires should be obvious,grey, white, purple, green, both solid and with black tracer, so separate these from the function wires ie, switched live, constant live, earth, night illumination, methinks the aerial wire is one of possibly only 2 left. (there maybe other groups of two for amps etc but these should be obvious (he says).
Once you establish the aerial wire on Toyota loom, cut it, taking one side to your switch. Add another wire to the other side of your switch and take that back to the loom. Connect the loom to the HU. With the HU on, the wire to switch will be live but will not operate the aerial unless you flip the switch.
There is the possiblity that one of the other members will have done the job recently, that being the case shout up!!!
On the night illumination from, I would put an tester on the Loom, and see which wire illuminates the tester when you switch the lights on and simply connect that wire to the orange HU wire.. OR you could pick up on a instrument light wire at the back of the heater dials and piggy back on it with a wire to the orange on the HU.
Phew, sorry so long winded!!

That's fantastic, thanks!
I got home and had a look round the wiring....instantly noticed the bullet connector for the aerial that I didnt realise was there... s:oops: :oops: s:oops: oops s:oops: :oops: s:oops:
As for the illumination wire, sounds like I'll have to do some investigation and hook up my electrician friends meter to figure out the offending wire on the main loom.
Thanks again s:D :D s:D
