got me a replacement reversing lamp but the old wires were both black! Anyone know what colour wires from the loom are for the unit. One must be earth so black but the other?

thanks:)
 
If the lamp has two wires it wont matter. If it only has one then with the ignition on( engibe not running) and car in reverse try each wire in turn to lamp. or buy a cheap multimeter.
