A. Locate the factory ECM. It is located on the
passenger side of the engine compartment at
the back of the engine compartment. There
are two.silver boxes. The one that is
attached to the firewall is where you will
attach the Paxton Engine Controller. There
are three plugs on it. You want the one with
the black plug. Look in the assembly draw-
ings and find drawing #1017718. This draw-
ing gives the pin locations and wire colors.
Mount the relay on the passenger side fire-
wall just to the left of the black plug. (See
Fig. 6.1-a.)

B. Run the power wire #30 on the relay, across
the firewall to the power distribution box
located on the driver side and in front of the
battery with a 13mm socket. Remove the nut
and attach the wire for the 12 Volt power
supply for the relay. (See Fig. 6.1-b.)
C. Run the ground wire for the relay #85 and
the supplied engine control unit to the stud
just to the right of where you mounted the
relay. This is a factory ground and should be
used. The trigger wire for the relay #86 is
attached to the red/white wire in the large
plug on the power train control. (See Fig.
6.1-c.)
