Lots of places proclaim to sell it - but quality of the insulation is never even close to the stuff I pilfer by the armload from the junkyard. Places like digikey or Mouser (where I get a lot of smaller electronics and internal wire) don't make life easy for me.
I am making a nice new, from scratch harness and I'd like a variety of color, size and all of the same high quality. Where do you guys buy your wire?
(Matt from DIY Autotune... that was nice stuff in a variety of colors that came in the squirt harness - care to share a supplier?)
