Additional: I spent some time removing the forward top skin in preparation for removing the cabin top so I can do the overhead console and finish the doors. I had forgotten what a working a lot of clecos was like. Whew!
In keeping with my plan that no wires or plumbing penetrate the firewall without a connection, the LSE coil cables needed a connector on the firewall. Since Klaus uses coax and both connections are active, the bulkhead connectors needed to be isolated from the airframe. These are from L-Com and are steel with nylon insert and isolator. The backside is pure nylon; I put the nut and lock washer forward for a little more flame protection. The BNC connectors attached to them will also tend to shield them somewhat. You can see the run from the LSE box to the firewall is not much and the coils will not be far from the firewall either. I'm probably making too big a deal of this but i have a vision. Once the connectors were installed, I tested with a multimeter to be sure they truly were isolated from the airframe.
