Extension cable for SAE
compatible OptiMates to enable them to be used further from the vehicle or
battery. Simply plug one end into the outlet lead of the OptiMate and the other
end into the accessory cable (e.g. eyelet lead as supplied with OptiMate, or another
SAE accessory). Heavy-duty cable to prevent Voltage drop. This new SAE
compatible lead is supplied with a detachable rubber sleeve to form
weatherproof joints with other OptiMate SAE accessory leads.
If your OptiMate or accessory has the white TM compatible connector, you need TM73.
