B. Black Wire(s) Labeled
– “Module Ground” & “TPS Ground”
Connection of these wires will depend on what type of throttle position
sensor you are using: one that is part of an EFI system or one fitted to a
carburetor or mechanically injected diesel engine.
Electronic Fuel Injection Systems
Splice both
, “MODULE” and “TPS”
ground wires (Pins 15 & 16
Black) into
the main ECU
ground wire.
Do NOT
connect the ground wires to sheet
metal or
other ground sources
. The
TORC Module MUST
be connected to
the Main ECU ground, as
close to the
ECU as possible. The reason
for this
connection method is because the
TPS
is shared between the two systems
and improper grounding will corrupt the
TPS
signal. Splices and a Posi-Tap
have been provided to allow this
connection.
If this step is overlooked there is a
good possibility the Throttle Position
Sensor (TPS) will not read correctly.
Carbureted / Mech. Injected Diesel
Connect the
“MODULE GROUND” wire
(Pin 15 Black) directly to the battery
ground post or negative battery cable.
Do NOT connect the ground wire to
sheet metal or other ground sources.
The TORC Module must be connected
directly to the battery ground post or
negative battery cable for the cleanest
(less noise) ground possible.
Pin 16
, “TPS GROUND” will be
connected on the following page.
