It really does not matter which wire you use, the important thing is to make sure you user the same polarity throughout all of the system connections. General consensus is to use the black wire to all of the negative terminals.

∙ 15y agoIt all depends on where the wire is installed!
In Direct Current systems, such as in a car or truck, a black wire may be negative but that should not be assumed. Always check first, using a voltmeter.
In Alternating Current household electrical wiring systems a black wire may be:
"Hot" in USA or Canada or other countries which use the same 60 Hz system.
"Neutral" in the UK in household electrical wiring done before 2005.
(After 2005 new household electrical wiring has to use Blue for Neutral, as for the rest of the European Union.)

AND
always use an electricians test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
