HEI coils, internally resisted coils, and most aftermarket ignition boxes do not
require the use of a ballast resistor. The
#920
wire will connect directly to the +
side of the coil. See the
NO Ballast Resistor Connection
Diagram
on page 34.
If an aftermarket Ignition box is being used, such as an MSD, Accel, etc., this
Black/Pink
#920
wire will supply the Ignition box with the switched power source
it requires. This wire will go to the aftermarket ignition box and not the Coil; the
Ignition Box will provide the Coil + connection. This
#920
wire may need to be
pulled from the
Engine Section
and routed to where the box is mounted. See
the Ignition box m
anufacturer’s instructions for a specific connection point of this
power source.
MSD Ignition Connection
on page 34 has been provided.
If you have converted to fuel injection and are using a standalone harness, such
as any of Painless fuel injection harness, and coil power is supplied though the
fuel injection harness, in LT1/LS1 and newer applications, this Pink/Black wire
will provide the fuel injection harness with the switched power source the harness
requires. If using a Painless fuel injection harness, this Black/Pink
#920
wire will
connect to the open ended Pink wire of the fuel injection harness labeled “IGN”
or “Fuse Block IGN”.
Route this Pink/Black
#920
wire to its proper
connection point and cut to length, install the
appropriate terminal for your connection, and
connect.
Terminals and a factory style connector,
seen in the photo at right, have been
supplied to allow connecting to the + side of
a HEI Coil.
An added bonus of the coil fuse is it also provides a
built in theft deterrent. Removing the COIL fuse from the fuse block when the car is
parked for periods of time will not allow the ignition system to function, making the
vehicle virtually impossible to start/run. What would be thief is going to trouble shoot
power to the coil?
“Ballast Bypass”
Locate the individually rolled 16 gauge Black/Yellow wire printed
<<COIL+>>
#970 BALLAST RESISTOR BYPASS <<STARTER SOLENOID "I">>
. This wire will
not be part of either of the harnesses provided, but a completely separate roll of wire.
This wire will only be needed if you are using a ballast resistor. Most installs will not
need this wire and can be omitted from the install.
On vehicles utilizing a ballast resistor, this wire is intended to connect to the
positive side o
f the coil from the “I” terminal of the starter solenoid and will provide the
coil full 12v of power when the starter solenoid is engaged by bypassing the ballast
resistor and going directly to the coil. This is done to facilitate starting the engine and
will not harm the coil. If connected to the starter solenoid correctly, as indicated on page
??, this wire will only have power when the ignition switch is in the START or “crank”
position.
