Anybody know if it's possible to make a 95 CD player work in a 90 Legacy, the one with the aux jack. CD player is installed, connectors from cd fit into radio, however there is a two wire plug coming out of the cd player but I can only find a single wire plug in any of the under dash wiring. CD goes in but no sound or lights. CD self ejects after several seconds. I cut and saved the two wire connector from the under dash side of the donor car. Any suggestions?
