I'm replacing my very dead Nakamichi head unit, trunk-amp and trunk CD-changer with an aftermarket unit and aftermarket sub-woofer amp.. I"ve located a System wiring diagram for the SC400 with the original Nak components and I've rung out most wiring tie-in's (after some digging and head scratching).

However, the original Nakamichi wiring diagram shows 3 wires out of the Nak head unit labeled "Auto Antenna Motor & Relay" (Blu/Wht, Yel/Red, Pnk/Grn). Since I don't have a full wiring diagram for the vehicle, I can't determine what each of these three conductors actually does AT the power antenna. Most aftermarket head units (mine included) have a SINGLE switched power conductor for control of the power antenna. How is this single conductor interconnected to the original power antenna wiring? Alternately, is there a schematic or wiring diagram anywhere showing wiring for the EXISTING power antenna?

Not trying to bump my own post, but I subsequently found some older forum threads that explained the factory power antenna apparently needs a switched +12V to rise and it MUST see GND to retract. However, I still can't find information on an explanation (or wiring diagram) to clarify which of the three wires from the OEM head unit does what function. Can someone still clarify that?

I found that the blue controller box on my power antenna is defective
