Electrical Help/Questions!!!!!
The wiring diagrams in the "Detroit Iron" 1974 Dodge CD show an 18 Gauge yellow wire to one side of the starter relay coil, at terminal "L". Then there is _EITHER_ an 18 gauge Brown & Yellow (for Auto trans cars) _OR_ an 18 gauge Dark Green (for Manual Trans. cars) to terminal "G", the other side of the relay coil. I wouldn't think the '73 wiring would be much different. Hope this helps.
