[TenTec] 302 encoder wiring question

[john ferro]

hi, i am having a hard time finding a 8 pin male to male din cable for the 302 encoder/pegasus combo. 

can anyone tell me if all 8 pins are used on the 302 encoder to remote jack on the pegasus 550? i was wondering if a 5pin male to male cable would work. it would fit the jack just fine. sometimes only a few pins are used, so i'm hoping that is the case with the 8 pin cable. any help appreciated.

thanks and 73, john
