Installation Instructions
Ensure you have the correct tools for the job. Read the instructions completely before starting to ensure
you are properly equipped. Disconnect the vehicles battery before beginning.
Ensure you have enough wire to reach your ignition power source, sensor or injector splice, ground and the
pump. Refer to wiring diagram at the end of the manual for the instructions below.
New Installation of Pump and Controller
1.
Connect sensor or injector tap wires.
Route the sensor tap harness from the cabin into the engine bay. This is the harness with a green and
black wire.
•
For 101000 models, locate the fuel injector wiring harness. Connect the green wire to the positive
injector feed, and connect the black wire to the switched ground for the injector. The positive wire
will be common among all injectors; the ground wire will be different for each injector.
•
For 101005 models, locate the desired sensor input source. This may be a throttle position sensor,
a 0-5V MAF (mass air flow) sensor or similar input. Tap the green wire into the sensor signal wire,
and the black wire into the sensor ground wire.
•
For 101020-101050 models, locate the engine MAP (manifold absolute pressure) sensor. Connect
the green wire to the sensor output signal wire, and the black wire to the sensor ground. To verify
which wire to tap, a volt meter may be used. Refer to troubleshooting section below for nominal
voltage outputs of the different sensor types.
Protect wiring harness by installing alongside or within existing wiring harnesses loom. Keep well clear
of sources of abrasion or excessive heat. Do not disconnect any sensor from the ECM, instead
piggyback on the same wires.
Soldering this particular connection is highly recommended. Alternatively, the installer may wish to
utilize two of the provided butt connectors containing integral heat shrink tube. Ensure these two
connections are water tight when complete so as to not compromise the original wiring or the sensor
output.
2. Locate a switched ignition feed.
The methanol injection controller should only be powered when the
vehicles ignition is on. Locate a switched 12V circuit that is on when the key is in the RUN position,
using an accessory circuit is not advised. Connect the red wire from the controller’s main wiring harness
to the switched ignition feed. Ensure 10A fuse is correctly installed in this wire. If the circuit being used
is suspected to already be heavily loaded, the use of a relay (not supplied) may be desired. To make
this connection, a switched power wire may be cut and reconnected with the controller’s power wire
using the supplied butt connector (non heat shrink type). Otherwise, this wire may be soldered and
insulated for protection.
If the installer wishes to be able to switch the controller on and off, install the supplied switch on this
wire by cutting the wire and installing the two supplied spade terminals. Installing this switch is
optional but is recommended.
