D. Connect ENGINE SECTION A wire #719 (pur) to the Starter Relay Start
(S) terminal.
E. Connect ENGINE SECTION A wire #720 (pnk) to one end of the existing
Resistive Wire. You may replace this wire with a Ballast Resistor. Your
Jeep may already have a Ballast Resistor installed. Connect the other
end of the resistive wire (or Ballast Resistor) to the Ignition Coil
POSITIVE (+) terminal with 14-gauge wire (you may have enough pink
wire left over to accomplish this). If you are using a Ballast Resistor,
mount it away from other wiring or hoses. It gets very hot during
operation.
F.
A 14-gauge wire connected from the Starter Relay (l) terminal to the
ignition coil side of the Ballast Resistor (or resistive wire) serves as a
Ballast Resistor BYPASS during engine starting. If you are not using a
Ballast Resistor (or resistive wire), this jumper is not necessary.
G. Connect ENGINE SECTION A wire #723 (pur/wht) to the Ignition Coil
NEGATIVE (-) terminal. This is the tachometer source. If you are not
using a tachometer, insulate and stow wire #723.
