Even I would be interested in more info on this project. Eventually, I'll be relocating both fuse panels to the center stack, where the radio used to be (on my Galant). If cutting is required, I'm cool with that, but I was thinking there might be some kind of aircraft electrical connectors which are provisioned for 20-30 conductors that could be used. Better to make clean cuts and terminate the conductors with AMP pins or something which clip into a larger connector that could be securely plugged into the firewall somewhere.

Just a thought. A quick search of mcmaster.com doesn't pull up what I'm thinking of...
