I posted this in the audio section as well. This is for all of you who do not look at that section of the forum.




I had to take a few minutes this morning to wire up a X920bt for a customer install.
So I figured now was the time to take some pics and makes some notes for everyone who has questions when it comes to doing this while installing you aftermarket radio in your C5

OK
First
we start with the roem-vet1 harness


next we take the section of the harness we are going to wire and unplug it from the roem-vet1. This is just an easier way of working on the wiring.


First thing I did and this is the most important part of the process.
The BLUE/WHITE from the radio will connect to the BLUE on the roem-vet1. If you connect blue/white to blue/white then your front door speakers will not work and you will be calling me saying this system sounds like crap! So do this step first!

Next step i did was to connect the yellow from the radio to the yellow in the roem-vet1

since everyone wants the bypass performed and your not hooking up the green parking wire. I like to cut off the extra wire and use this as an extension for the red ignition wire on the radio harness. As you can see i connected these two together as this will allow you to run to the ignition source which in most cases(97-03) you can run to passenger footwell to the yellow wire that is taped off. (there is also a black and orange wire there as well)

pic of wire instsalled in footwell
note this pic is from a prior install so the wire used to extend is purple just note that above for current install i used a green extension

next step is to connect the speaker wires.
This is a matter of matching color to color. NOTE the roem-vet1 has three wires for each speaker. YOU WILL NOT BE USING THE LOW LEVEL SPEAKER WIRE, ONLY THE HIGH LEVEL.

for the most part after this your pretty much done.
Your wondering about the ground wire. In this install we did the bypass on the x920bt which was moving the one yellow/black wire over one notch in the connector. We then took the yellow/black wire we moved, the parking wire and the black ground all form the radio and conencted them to the black ground in the roem-vet1

only other wire you will need to worry about is the dimmer wire
to connect the dimmer wire we spliced inth the hvac control harness.
The orange white wire from the radio harness was extended using a left over piece of green and then connected to the cream/yellow colored wire on the far right of the blue side on the hvac connector


I hope this helps everyone out.
If not you know I am always a phone call or email away form helping out as well.

Nice tutorial Dennis. I still think if I ever change my audio system, I'll leave it to the pros.

Nice work, Dennis.
Suggest you add wire routing and location for antennas for Sirius, GPS and Bluetooth and wire routing for rear view camera.

Dennis,

On my 2004 I looked for that power source you show in your pictures. It was not there. Instead I used the ignition switch wiring.

I hope that was my X920bt you were wiring up. Nice write up and pictures.

Dennis I just got the Kenwood 6980 in from you and I'm just starting some of the wiring.

I'm confused about the bypass. You said to take the yellow/black wire and move it over one spot. There is only 1 yellow wire on the radio harness and the OEM-1. I must be missing something there. I will start wiring and post pics of what I have so far.

that is the bypass for the pioneer.... on the kenwood you just send the parking brake wire to ground If I remember correctly

Thanks man! Am I missing a writeup for the Kenwood or is it pretty much the same?

Here's what I have right now.

Kenwood 6980

The left is the radio harness and the right is the harness that connects to the OEM-1.

All matching wires are connected.

What is not hooked up are the ones with the labels and are pictured. I don't plan on running the dimmer (orange/white) to the HVAC. I never dim my dash lights. Also the two long ones. The long green one says PRK (parking) and the long purple one w/white stripe says "reverse". Other than that there's the black ground and red power not hooked up.

So can I take the parking (long green) and black wire from the radio harness and run them to the black wire on the OEM-1 harness? Then cut the "reverse" wire and use that to extend the red from the radio hardness to the taped up yellow wire in the footwell?

Nice and clean

Nice work, Dennis....will do this some day for sure. Now, can I have meat sauce with my spaghetti?

Thanks Dennis! I will keep updating this thread and hopefully it'll help someone else like me who was searching for step by step instructions w/pics.

Tomorrow or Friday I will pull the dash and run the GPS, MIC, and power wires. I'm off all next week so I'm sure it'll get installed.

Thanks I was checking that one out as well.

So what's everyone using to cut the radio shelves out? Does this ultimately get mounted with just the two L brackets?
