Electrical Routing

I'm at the point where I need to start planning electrical / coax wiring runs throughout the fuse and need some guidance. Several months ago someone was asking for the same advise. Replies included several website links with good pics of various wiring runs particularly from the rear & baggage area up to the front. Now I can't seem to locate the thread.

I'm interested in how/where wires are routed from under the baggage floor up to the front. Can wires run through the tunnel? Is there a "safe" place to drill without hitting the rear wing spar?

Thanks for any help or pics on this.
