i bought a new sony xplode cd player for my 1999 ford mustangi got the scosche wiring harness fdo21 and it just doesnt match up to the wiress in the dash even though it says ford and has the the right year on the box
that wiring harness you bought gets wired to the wiring harness from you new head units wiring and plugs into were you unplug ed your factory head unit from.they call it plug and play.do not cut the plugs off your wiring harness under the dash.all wiring done on a bench tape or cap all contacts even the unused ones so you have no shorts.then just plug each plug into its own plug in.there's only one way they will fit and remove the contact covers in the plugs before you plug them in.and follow the wiring diagram that came with it the colors match up if you have the right make and yr and model of the plug in that fits your car.the (color code gets matched to the new stereos wiring)has nothing to do with wiring under dash,this is why you bought the plug in in the first place so you did not have to deal with all the dash wiring,it should plug in just like your factory stereo did.
