I am trying to find out which CDM pin goes to which pin on the Bose head unit for a '94 STS Stereo. My head unit is model #16166166. the CDM has the inputs & outputs marked on the case - "14V" , "HGRD" , "DIM" , etc , but the Bose just has two unmaked connectors.I don't know which pins of the two connectors on the Bose head unit to connect to the corresponding pins on the CDM. Thanks for any help you can give me.
