Thanks Adam, The Manual was what I was looking for. For reference the Icom America part # for the fan is 2710000701 and is in stock w/the cable. $13.16 USD + shipping. The number in the Service manual is for a manufactures part AD0612MX-C70GL-LF which is available from Mouser Electronics for $9.99 + shipping w/no cable. Edgar, N6OU
