Greetings all! I am on the last leg of a long journey....putting together a complete C70/SC-901/Dynaudio/HA-7400 audio system into my 99 S70. I have enjoyed the SC-901/ Dynaudio system now for a couple of years powered by the capable, but high THD, HA-4350 (Volvo Part #9496597). (BTW, major kudos to Jim Rothe for putting the SC-901/Dynaudio info together! He should get a commission from Volvo - otherwise who would ever know that the kit was available?) <p>I have secured a HA-7400 on ebay, but need the wiring harness that connects the amplifier to the Sc-901 head unit to complete the journey. Does anyone know the correct Volvo part number for this audio harness? I already have the cd changer din cable. I just need the harness for the amplifier to connect to the head unit and power the speakers. Thanks for any info that you can provide!
