Hi all. Have done heaps of stereo installs the past but only in holdens... The cruiser has me stumped. I got a pioneer head unit 2din and the factory unit has a permenant loom of wire in addition to the usual plugs which i dont know what to do with.... Just cut it off and tape it up? This should be an easy job but even the net has let me down... If anyone can tell me or direct me to a how to video or guide i would be greatly appreciative and if there is no vid i will make one for future. Cheers guys n gals

Hi Ross,

Not sure what Cruiser you are working on.......may help a little.

I'm pretty sure that if the wiring gives you an issue, you can buy a plug in adapter loom.

Maybe not the whole answer, though maybe it is a little help.

Cheers,
Wayne & Sally.

All good :-)

Thanks for the response. I am aware of a patch loom/iso harness to connect the native toyota loom to the pioneer head unit harness but i am still left with the issue of the hardwired connection to original toyota head unit. This connection seems to be additional to what is required by the pioneer head unit. is there some splicing required or can it be left disconnected and insulated after installing the pioneer head unit. Also for entertainment sake, what is the purpose of this hardwired connection?

Take it to a stereo installer may be cheaper in the long run than cutting wires that shouldnt be cut

Have you chased that "Permanent" loom any further?
Surely it must have a plug somewhere close.

after closer inspection the hard-wired group connection originates from one of the other plugs... My guess it is a constant power supply for the stereo but can't say for sure... I suppose it's time to replace my multimeter and start investigating. As a side note, I am stunned at the lack of info on this topic to be found on the net..... Gazillions of people own 105 series cruisers and I bet the majority of them have replaced the factory stereo. Furthermore cruiser owners tend to be pretty handy and like sharing info... Maybe I will have to fill this information void when I figure it out.....?

Ross, I have a late 2002 HZJ105, which is the update, some of the wiring is a bit different to the 98-02 model.

Like you I ditched the Toyota head unit, was never going to use it again, and I also fitted some rear speakers at the same time as replacing the head unit.

I made my own wiring plug setup.

The Toyota vehicles of this era were all pretty similar. Here is a link to a Prado installation I wrote back then:http://www.lcool.org/technical/90_series/radio/radio.html
The connectors are probably the same as yours.

Hey Phil, thanks for the link... I had ready seen that one. The install itself is not bothering me just the fact that there is this extra round plug that has no detachable connection... Goin to have another look today and make a decision on what I am going to do. Cheers

Hi Ross
What I used was a plug harness that goes from the toyota to the plug harness suplied to for the pioneer , you have to solder this together, and the bloke I purchased from was very helpful with the connections . It is fairly easy once you get going.
Part Number is AP1761 cost $ 17.50 from Top Audio on e/bay

Thanks for all the help... Turns out from what I can gather it is just power supply and control functions for the cd player below the radio... The permanent loom is piggybacked onto the plug on the head unit side of the connection so once unplugged from the vehicle loom, it remains as part of the head unit... Feel a bit stupid after all this conjecture now... Will still post a vid of the install for future anyhow. Thanks again and will put a YouTube link in here once done. Happy easter
