Firewall

[mbagge01]

I am interested in installing a radar detector and was hoping someone may know where the firewall on a 955 CTT can be accessed to route wires into the cabin. Are there grommets on the firewall like on audi's that can be used to get through the firewall.

There are....probably the easiest place to access would be driver side....pull down the knee plate and go through where the pedal cluster is roughly (there are a LOT of other wires in there).

But can i ask why you need to go through the firewall? The battery and switched power is all inside the car (battery is under the seat), fuse boxes are in the dash.....

It sounds like it may be one of these "hidden" installs where there are sensors in the front and rear of the car that need to be wired to the inside receiver.

It is a hidden radar install so a few wires need to be passed through the firewall to the front of the car.
