Re: Help changing points to HEI
Yes, green wire from OE harness is tach.
Connect it to TACH terminal of HEI, next to BAT terminal of HEI.
Ceramic resistor is not OE design. If supply wire is cloth sheathed, has a cloth coat, this is the OE resistive wire from ignition switch. You should run a new 12 AWG wire from IGN spade on fuse panel to HEI and tie back and insulate the cloth wire.
