Mallory Ignition ACCEL timing computer 49340 - Manual (Page 10)

T HE 4- PIN , F LAT , I NPUT C ONNECTOR
he 4-pin, flat connector is your A CCEL T IMING C OMPUTER ’s main power input.
It also inputs signals from the N 2 O actuator
for Nitrous timing retard.
R ED Connects to +12 volts.
B LACK Connects to Ground.
G RAY Connects to the Black ground
wire from the N 2 O actuator.
Y ELLOW Connects to the Red +12 volt
power wire from the N
2 O actuator .
T WO RPM-A CTIVATED 2- PIN O UTPUT C ONNECTORS
ince both connectors are powered and switched to ground inside the Timing Computer,
ither connector can be used for any RPM-Activated device. Neither needs an external
witch or power source. The RPM-1 Pink wire and the RPM-2 Red & White wire supply
ontinuos battery voltage. Both RPM-Activated switches can drive multiple solenoids.
Please, be sure to wire the correct connectors to their correct solenoids and devices!!
T HE S QUARE , F EMALE O UTPUT C ONNECTOR
he square, female plug is the T IMING C OMPUTER ’s
main output connector.
Connect it to an A CCEL + ignition, OR
Connect it through your A CCEL 3-S TAGE
R EV - LIMITER to an A CCEL + ignition.
In either case t he square, male (input)
connector should already be in place.
If it has not yet been wired,
see the A CCEL + Ignition’s manual.
Remember: when using an A CCEL 3-Stage Rev-
miter, you must use an A CCEL + ignition system,
with DIP - S witch-4 pushed up) .
using your A CCEL T IMING C OMPUTER with any
xternal rev-limiter, the rev-limiter is placed
etween the Timing Computer and the A CCEL +.
The Square, output
connector plugs into
an A
CCEL + ignition or
an A CCEL 3-S TAGE
R EV - LIMITER .
To an A CCEL 3-S TAGE
