Connect battery charger '-' to '-' of battery and '+' of charger to '+' of battery. The battery charger is a BATTERY CHARGER. The car connexions or polarity are irrelevant to the battery charger.

However, i would be cautious not leave the trickle charger on the battery continuously for more than 2 or 3 days at the max without checking water level in the battery.

Charging a battery depletes the **WATER level leaving higher acid concentration **. So CONTINUOUS charging for LONG periods of time is or may not be a good idea. I never use trickle chargers on a continous basis for more than 2 or 3 days and that's only if the battery is dead to begin with or i plan to operate the equipment in a few days or there are some other unusual circumstances.

Trickle charges CAN FRY a battery over a long period of time, ESPECIALY small batteries such as motysickle batteries.

IMPORTANT: Let the battery charger warm up for about 30 seconds or longer BEFORE connecting to battery. DO NOT BELIEVE THE MODERN INSTRUCTIONS OF ANY charger that states to connect to device BEFROE plugging in charger to wall outlet.

when DISconnecting the charger use safety glasses and hold your head AWAY from the battery as far as is comfortably possible. Batteries produce hydrogen gas WHEN CHARging and there IS a remote chance of a spark occuring especialy in confined spaces.
