1) Studied Lightspeed Manual for routing of inputs and outputs to engine. 2) Routed output coax cables through existing firewall penetration (brown cables) 3) Created new oversize hole for input cables from sensors. Hole had to be oversize to allow sensors (2) to pass through firewall. 4) Routed input cables through hole, and reduced opening with firewall pass-through plate. 5) Installed mounting plate for upper sensor at top front of engine. 6) Installed mounting plate for lower sensor at bottom front of engine. 7) Roued cables along engine top and bottom, respectively, and mouted sensors top and bottom front. 8) Secured sensor cables with adel clamps and snap ties.
