Has anyone had experience hooking up lights for a small boat trailer to a Saab 9000? I understand that one should use an isolated converter (European light system to U.S.) so that no current is drawn from the existing light circuits. Otherwise it may screw up the sensors that indicate when a tail or break light is burned out. Such a converter requires an independent hot lead. The only hot lead I can find in the trunk area is for the truck light. Its wire looks too small to carry all the current for trailer lights. I hate to run a wire along the bottom of the car to the battery. Is there any other source of power accessable from the trunk of a 1994 9000CSE? I did find a free female connector on a foot long wire bundle leading to the wiring harness near the driver's side tail light. This connector has all the appropriate signals for a trailer (brake, parking, left and right turn) but no independent hot line. Does Saab use this for a trailer with the European light system or is it just used for diagnosis? If it is designed to handle trailer lights then I should be able to use an ordinary (non-isolating) converter with it. Your comments are welcome. Ramsey Frist
