3 For engine users desiring to fabricate their own
wiring assemblies. The four proprietary connectors
needed may be obtained from Ford PPO or from the
parts manufacturers.
4 Note the wire loop from UESC pin 6 to pin 7. If the
engine is operative with low octane fuel it may be
necessary to retards the spark. This may be done by
cutting open the loop and grounding the wire which
goes to pin 6 or 7 or both.
To retard l-2" ground wire to pin 7
To retard 2-4" ground wire to pin 6
To retard 6-8" ground wire to pin 6 & 7

The UESC module must be mounted somewhat
above the level of the intake manifold. This is so
that fuel or condensed fuel vapor cannot drain (thru
the vacuum line) into the module during operation or
storage. (Reference service adjustments portion of
page 2B-02 .)
