hi i have a pioneer deh-2400 (no wiring harness) and i need to know what other pioneers use the same plug
All of the pioneers around the year that model came out will have the same plug. I'm not sure if they are still using that same harness currently but you can check at best buy/circuit city. They will have a harness for pioneer radios that you can try. If it doesn't fit then you can always return it. Good Luck!!!
