Here is what each wire of the PAC OEM-1 model is for

I attached below the installation instructions PDF for this model for GM

AH! I think I've figured it out!!!

So my stereo is a Pioneer Carrozzeria AVIC-ZH9000 and as an extra, you can purchase 4 black wired metal antenna's to help with the Japanese GPS system (pictured below, now discontinued)


Would we agree these wires look VERY familiar with the plugs in the back of the stereo?


I know I have windscreen antenna's (but will have to check how many in the morning and hope I see 4) and it would explain why they group together and head behind the dashboard

The 4 black wires are clearly something to do with the aftermarket head unit possibly tv ariels so I would look to remove them the pac lead I wood convert to a euro male iso plug ( as most reasonable aftermarket headunits ie kenwood alpine Sony pioneer etc come with female iso) I have got a wiring guide I can send you of what each of the wires for the pac lead does once converted it will plug straight to headunit won't be able to send wiring diagram till new yr though

 

[Krusty]

I've just gone out and checked, I do have 4 antenna's on the windscreen, each with the same gauge black wiring coming from them. So happy to say that is to do with them worry over.
Now I can concentrate on the 16 wires that go in to the Pioneer plug.
The new stereo I've bought has 2x 8 wire plugs (male) as shown below


and they fit in to here


If you could send me the wiring guide, that would be a HUGE help

The back of the unit in C5 now has labels on the back to see what each connector is for

What's this a pic of def isn't the back of a stock c5 corvette head unit ? If I am now confused with what your posting team zr1 I am even more sure the OP is really confused

 

[teamzr1]

I meant the radio his C5 has installed as of now, Pioneer Carrozzeria AVIC-ZH9000
which is not a stock GM one

2001 Chevrolet Corvette Car Radio Wiring Diagram - MODIFIED LIFE

Question: Where can I find a 2001 Chevrolet Corvette radio wiring diagram? What are the 2001 Chevrolet Corvette radio wiring harness color codes?

A lot of the labels aren't there.
I'm definitely on to a winner I think... the Carrozzeria wires that are connected to my current unit are as follows:
Main Antenna (disconnected and ready to fit in new stereo).
GPS wire (no longer needed in new stereo).
AV IN•OUT (not connected to anything and not needed anyway).
Reverse Camera (never worked and getting a new one with the new stereo).
TV/GPS Window Antenna labelled 1 2 3 4 (no longer needed in new stereo).

That means I only have the main power plug for the stereo left, which consists of 16 wires.
Perfect, because the new stereo has 2x male ISO style plugs, 8 wires per plug = 16 wires
I just need to determine what wires do what from the PAC to the plug (which I'm hoping Custom exotics can provide), solder and shrink them to the new relevant wires.
Then I'll grab the fire extinguisher

In my post of #21 I included a PDF and a URL showing what each wire of the PAC OEM-1 is for
Does the new radio include what each pin of the unit is for to match up with the PAC wiring pinout ?

 

[Krusty]

The new stereo does have what each wire is allocated to do, so will just be a case of matching the pin out as you say.

If anyone needs any help, I managed to find the OEM-1 PAC function colours. They are as follows:


I'll keep you updated with my install, and hopefully all of this will help someone else out

I made it easier to read when printed out

Yeah that's it you just don't use any of the low level speaker connections
