I installed the 40 amp shunt that came with the dynon package. I located it on the Right side of the firewall and positioned the starter switch next to it. They will have wire run between them. I attached the High and Low amp transducers from the Dynon package. Shrink wrap everything I can as I feel it keeps it clean and secure. I also drilled and installed firewall sleeves. Through those I ran the sensor wires. I drilled two one for the bulk of the sensors and the other for the exhaust gas sensors. I have sheathed all my wires in expndable wire sheathing from ACS. I have been using this as it works realy well to keep the wires together and it is durable enough to add plenty of protection against any movement.
