Re: 77 WAGGY WIRING FOR IGNITION MODULE?
OK, assuming both the factory manual and my Chilton's are for the 401ci V-8 (they just say "V-8, 1975-79"), here's the colors/destinations. BLACK: ground (on 70s FSJs, this is a constant). GREEN: coil, negative side. WHITE: distibuter, female side of the plug. BLUE: distibuter, male side of the same plug. RED w/color stripe: switched power, although the Chilton's shows it tying into the "instrument cluster" fuse and the "transmission kickdown" (auto only) fuse. The wire also connects (thru a splice) to the positive side of the distributer, carb solonoid (if equipped), and the voltage regulator. Power should come from the "run" position of the ignition switch, although it should also be live in the "start" position as well.
