Mallory Ignition ACCEL timing retard module 49355 - Manual (Page 6)

When connected to an H-Pattern, manual transmission, your Timing Retard Module’s 1 st ,
nd , and 3 rd keys each program how much retard takes effect when one gear is selected.
nstall switches on the shifter that, when closed, signal the module that a gear is engaged.
When the A CCEL Timing Retard Module receives its signal it adjusts timing retard to
e value you have programmed for that gear.
ypically the 3 rd key, and its switch, is attached to

keys, and the SAVE button.
When you shift into 3 rd gear its switch, connected
by the D K G REEN & W HITE wire (Connector Pin-C),
is tripped and ignition timing retards by 9°.
R EMEMBER : the 2 nd button refers to the second switch, NOT 2 nd gear!
In this example the 2 nd key, and its switch, is wired to 3 rd gear.
W IRING AND P ROGRAMMING AN A UTOMATIC
T RANSMISSION (Shifted Manually)
Automatic transmissions and their shifters are programmed, and
wired, like manual H-Pattern systems, except the retard switches
are connected to the shifter in a straight line.
As you shift gears, the values programmed take effect; each gear
with its own programmed value.

a value of 15° into the module
with the 3
