2004 GS 430 Mark Levinson Audio Wiring no sat nav

Recommended Posts

Hi there guys, I have a couple of queries about the audio connections that are attached to the stock Marl Levinson amp and head unit found in the second gen 2004 GS 430. (It does not have sat nav.)
I have been searching for a few days now and I still don't believe I have the correct information.
I am looking to install a double din head unit running 3 seperate Amps (2 to power 3 subwoofers) a 10 inch stock replacement and a twin 12 enclosed box in the boot, as well as a four channel amp to power new 4 inch composite speakers replacing the original door speakers. So I know what gear I want to run.

The problem I am having is that I cannot seem to locate a wiring harness adaptor that will mate with the speaker and live connections in the boot that are off of the original Mark Levinson amp.

So my first question is where can I find a wiring harness adaptor that will fit the stock speaker and power connectors? (not looking to keep cd changer) I have heard that some toyota adaptors are the same but I don't have specific information.

Failing that, I will have to cut and splice the wires into a different 16 pin connector so I was looking for the correct wiring diagrams for the audio/radio for the GS 430 2004 model.
If anyone has the right one available then name your price lol

My third and final problem is that I was told that there are no double din adapter fascia plates available for my car, however so far I have found four different models listed as follows;
CT24LX06 
CT24LX07
CT24LX14

Metra 95-8152
again if anybody is able to let me know which one fits best I would be very grateful.
As I am being told that they fit the second gen gs but only up until 2003 year and I cannot see why they would have changed the interior of the 2004 GS in its final year.
Thanks in advance, and audio upgrades wont be the only thing getting overhauled on this beauty this year

Where are you located? I have a double din fascia, which you are more than welcome to check the fit of.

Oh right okay, well I am based in Ipswich, like I said the double din fascia plates I have found list the second gen gs but only up til 2003 are you aware of any interior changes that would make my 2004 model interior any different? Are you able to tell me where you sourced your double din fascia kit?
Also are you aware of any wiring harness adaptors that would adapt the stock speaker connections? Or a diagram that would help me to figure out how to cut and splice in to a new pin connector?
Thanks for your reply

Mine came from eBay, and is the CT24LX06 one you mention. I can't think of anything outwardly visible that is different, unless they changed the brackets that the stereo and climate control bolt on to. The double Din install link in my signature might help to see if the pictures shed any light on differences.

 

for wiring diagrams, I uploaded these a while ago, but not sure if they'll match yours or not.

That's great, thanks for your help. If anyone else has any personal experience and can doubly confirm it would be a bonus.

Offer still stands with the double din fascia I've got. I can post it, or I'm heading past Ipswich on Saturday 27th May at some point as I've got a week on the Norfolk broads starting that day, if you want to test fit it.
