Glove liners - plus/minus - electrical question

[stopintime]

One harness - another liner - mixing and splicing harness components....

If I cut my harness, I have two pairs of wires. Plus and minus in each pair.

I don't know, but I assume it's best to have the current flow the same way in both liners....

Holding a multimeter in my hand - what's the next noob step to determine which wire is plus and which is minus?

With harness plugged in and power on, measure current from wire ends.  if volts are +, then the wire with the red probe is hot.  If volts are -, then black is hot. 

Alternatively, you could plug it in and see which wire has continuity to some other ground on the bike.

Thanks  ... and if the wires, going into the glove liner plug, are not identifiable... I can probably do the same thing with the plug, while the wires are temporarely spliced (?)

I am assuming you have a harness for the liner and a separate harness for the gloves, but you only want to have one harness installed on the bike.

I would measure continuity across the plug (from harness to the cut wires where the glove used to be). 

If you do not have a bike harness for the gloves, then it seems to me that standard practice for the "bullet" type plugs is to put ground (-) on the outside so you don't accidentally shock yourself.  After you cut, you can measure continuity from the outside of the plug to identify the - wire.

Old harness - wrong plug for new liners - getting new plugs on a piece of wire, from the liner manufacturer.

Your advice will help me get it right - thanks
