Question about 1995 Ford Ranger Supercab
I am trying to find out what color wires are for speakers,ie.left positive,left negative and right side as well on the original wiring loom that goes to radio.
On new systems, like the one you bought to replace old one: grey and white are front, purple and green are rear. New wires should be labelled or shown on diagram on radio body. Stripes indicate negative side of speaker.
On your old loom: cut back behind plug, and strip wires at ends. Isolate power and grounds, and any that go hot EVER! Now checking just the remaining wires, use a AA or 9-volt battery, and touch pairs of wires to opposite poles of the battery. If you touch two that go to the same speaker, you will hear a slight static sound at that speaker: label these for that speaker, and so on. Once you get the pairs seperated and labelled by speaker location, the negs will be the striped ones, though you may not find they all have stripes. once you pair them, test in both polarity positions, the correct one will sound better right away. Should be able to reach max volume with little buzz or distortion. If not switch pow and neg sides. Hope this helps, TT
