I began organizing the wire runs from the engine to the firewall. On the left side I ran the CHT, EGT and Lightspeed ignition wire (from the flywheel sensor) along and up toward the denter firewall. I spent a lot of time securing these wire runs with cushioned clamps to the engine mount. I was careful to leave enough slack to allow for engine vibration while insuring that the wires would not rub areas that would cause abrasion.
