Mallory Ignition ACCEL timing retard module 49355 - Manual (Page 10)

HE 2-P IN , I NPUT C ONNECTOR (Main Power)
This is the main power input for
your A CCEL Timing Retard Module.
Its B LACK wire is Grounded and
its R ED wire inputs + 12 VDC
from the battery.
(not more than + 18 VDC
or less than + 8 VDC )
In general, the best place
to Ground the B LACK wire
is on the engine.
Make sure that rubber
mounted engines are
well Grounded.
The R ED wire
connects to the battery
through the power or
key switch.
T HE S QUARE , I NPUT C ONNECTOR (Trigger Input)
he A CCEL Timing Retard Module takes all kinds of triggering, except Distributor-less.
s digital micro-processor controls are as sensitive as your trigger, and we recommend you
se an A CCEL Crank Trigger or Billetech Distributor. The triggering inputs are read either
hrough the Square, Male connector’s P URPLE and O RANGE wires, or the W HITE wire.
he W HITE wire typically gets its
quare wave input from:
• All Points ignitions
• Some
HEI modules
• Most Fuel Injections
he P URPLE and O RANGE wires get
heir inputs from either Magnetic
ickup or Crank-triggered systems.
he P URPLE wire is the Positive (+)
nput and the Orange wire is the
egative (–). See chart at right.
your system uses the W HITE wire,
ou must isolate and insulate both
he P URPLE and O RANGE wires.
your system uses both the P URPLE
nd O RANGE wires, you will isolate
nd insulate the W HITE wire.
he L IGHT G REEN wire connects
irectly to the Tach’s signal lead.
* Older A CCEL Crank Triggers may connect
W HITE to P URPLE and B LACK to O RANGE
T HE 4-P IN , F LAT C ONNECTOR (Input from Switches)
his connector receives signals from switches telling the module when to adjust Timing
etard. You do not have to connect all four switches. (See Wiring Diagram on Pg, 8)
