Anyone have any experience with:

1. Laser Jammers. Looks like they have become pretty sophisticated and it looks to me like two sensors would really protect the front of the A4, the way it is constructed with the rounded corners and headlights.

2. An easy way through the firewall to route the wires for the control module.

Thanks.

For getting through the firewall, you might read the current thread about the JB4. The install instructions for it detail how to bring the OBD connection into the car from the engine compartment.
