Cutting cables is usually a bad idea....but... here is a run down of what my "reference" says for the 96 radio with cassette. O/R - RR speaker (-), BR/BK - RR speaker (+), DG/O - RF speaker (-), W/LG - RF speaker (+), GY/LB - LR speaker (-), T/Y LR speaker (+), LB/W - LF speaker (-), O/LG LF speaker (+). Hope it helps. I want to get a factory CD readio player to replace mine and am hoping to "stumble" on to one that plugs into existing wiring.
