Where exactly does the antenna cable route through the interior? I know what was in the car isn't exactly proper, a previous scientist ( I think he studied Darwin) actually brought it into the cockpit at the hump under the center storage compartment, yes boys and girls, the one right over the driveshaft! I did remove what remained of the cable and patched the hole a long time ago.

My aim shows it running down the drivers side under the rocker cover then up up under the dash above the steering column to the passenger side of the radio. If you lik eI could scan this and e-mail it to you.

Thanks for offering to scan, probably not necessary though. Seems I had read on here earlier that it ran down the center and that just didn't make much sense.
I'm taking the rest of the week off to get as much finished up on the car as I can.
Thanks again for clearing that up!

My antenna cable had never been ran when I got my C3. It was in a roll zip tied to the frame. I found that the old one had been cut off and a new antenna assemby installed. The remainder of the old wire was still in place. It entered the drivers compartment through a rubber grommet installed in the storage/battery box behind the driver and then when down the rocker channel, up over the steering column to the radio.

Maybe thats helpful.
