Hi.anybody tell me dana full circle cruise control...four wires from connector under dash to unit ....On/ Off/ auto switch/ on dash..all wires are red with some thin colours.whats important is ..Do all wires to the cruise unit need to be 12v powered at the ignition on stage or is it just the ignition wire to the unit that needs 12v power..to start to work . .If you know I'd appreciate the information, or maybe a readable "wiring diagram" for a 1965 or thereabouts full circle cruise control unit..Thank you Anthony
