The Previous Owner had removed the OEM Becker 754 from my '87 SDL and I would like to use it in another vehicle.
I found a previous post showing the Power Wiring, but there is another "plug" socket on the back of the radio with multiple pins and I have no idea what they are used for.
One reference in a manual suggests these may have something to do with the anti-theft feature. If so how does it work and how is that wired?
Does anybody have a Manual for this radio?
