Raymarine L750 - Sidelooker Option; Fig. 2-15 Installing Cable on Transom

L750 Fishfinder: Installation and Operation Handbook

Important! The L750 Fishfinder is sometimes used with the
Raymarine SL70 “Pathfinder” radar display. The two units have the
same case design. Each unit has a large connector on the rear of
the case. On the radar unit, this connector is used to bring in the
radar signals. On the Fishfinder, this connector is used for the
transducer cable. If you have installed the two units side by side, be
very careful not to attach the radar cable to the Fishfinder, or vice
versa. This can cause permanent damage to either unit. The cable
for the radar unit has white insulation.
