SP Line AUI- AUI+ M/L AMP SYSTEM cannot use GGD1317. Because, external connector is different from pioneer AMP and M/L AMP(PIO:24P-20P,M/L:25P-16P). Moreover, GGD1240 which is a previous jig cannot be used (Because the signal array is different). Therefore, when the head unit of the M/L AMP system is repaired, pioneer AMP system is used. - Page 23 SP Line (To DC Regulated Power Supply) M/L AMP SYSTEM cannot use GGD1317.
