Stagea M35 - Stereo Harness Help Needed - Total Mess!

[shaks247]

Hi All, 

The Stags finally on the road after weeks waiting on the UK drivign agency to send me the registration. Now I need some help with identifying the harness behind the stereo and also getting the correct ISO harness so I can hook up an android head unit. I have picked up a ISO harness based on the info on the forum but its not correct and won't any of these connectors. 

The wiring in the car is a total mess with what looks like to be various attempts to install aftermarket ICE. FYI - the stereo it came with was the mini disc player and 6 disc cd player/radio. There was no factory option screen/tv but there is a factory reverse camera on the trunk. No idea where the feed for that is!

Here are some pics of the harnesses.

 

 

Thanks

Heres an idea of all the f*ucked up wiring I'm pulling from the car. Good news is outside of the wiring and a weak tailgate struts the car is solid and everything else seems to be working.

Ok, took a while but I've stripped out all the non-oe wiring (I think).

I found these two things under the passenger seat carpet. Am I safe to assume that these are not from factory. Etiher way there gone now anyway. 

 

This is what I've found so far under the steering wheel. Anyone know what the white and brown connectors are? and where they connect to?

I'm assuming the whatevers happend to the wires being spliced into them is not normal.

So I think I've figured out the stereo wiring from searching on the forum for a few hours.

I have question about the really thick yellow wire. This disappears somewhere behind the glovebox it was running along the passenger side of the car but not connected to anything. - Is that an OEM wire? 

Another Question - I have a factory reverse camera on the trunk. Should there be an independant wire from this to OEM HU?

Can anyone help out with the yellow wire question?

Quick update: I've fixed the cut speaker wiring, got my ISO harness and connected the new HU. Good news, it powers on. Bad news - NO SOUND!!!! Not even any static. I've searched SAU some posts mention a factory amp and convertor. Would this apply to the PM35 I have with a non-bose HU? Also, where would the factory amp be located? I've checked passenger side rear arch and its empy. 

Thanks!

Am I correct in thinking that the non-Bose HU are non-amplified? - everything on here seems to say they are not amplified, but want to check.
