ECU INSTALLATION

MOUNTING THE ECU

To install the ECU, locate an easily accessible area that does not obstruct the normal

operation of the vehicle (preferably under the dashboard to the right of the driver's side of the

vehicle).

Mount the ECU with the wiring harness connector opening facing downwards (so that the

open part of the ECU case would be facing down).

NOTE: Position the ECU as to not interfere with the normal operation of the

vehicle.

To mount the ECU to the vehicle use hook and loop tape, tie wraps or

screws.

If hook and loop tape is used to mount the ECU, attach the loop half to the

back of the ECU, and attach the hook half to the vehicle. If tie wraps are

used, put them through the screw holes of the ECU case. If screws are

used, try to use existing holes to avoid any modifications to the vehicle.

CONNECTING THE ECU WIRING HARNESS

The ECU wiring harness consists of 12 coloured wires. Only 8 of these wires

are required to be connected to specific points in the vehicle's wiring system

(see table). 4 wires are used to connect optional accessories.

Prepare the ECU wire harness by stripping all wires 2 to 4 cm, and apply

heat shrink tubing to all wires except the red, black and white wires.

Solder the terminal ring to the black ground wire in the wiring harness.

Connect to a ground point with the metal crimp ring and nut provided.

NOTE: The ground connection is made first to prevent any damage to the ECU.

Using the multimeter, locate a continuous unswitched +12 or +24 volt source in the vehicle's

main harness. Test the source in all ignition states including Start and Accessory. The +12

or +24 volts must be present in all states. Connect the red wire in the wiring harness to this

source (follow next two steps for instructions).

NOTE: This source should be connected to a source with a 10A fuse.

Locate a section of the +12 or +24 volt source wire that is close to the vehicle's fuse box.

Using the wire strippers, expose a 2 cm section of the wire (see diagram).

Twist the exposed end of the red wire in the wiring harness to the exposed section of the

source wire.

Using the multimeter, locate a +12 or +24 volt source in the vehicle's main harness that is

present only when the ignition is in the Start and On state (not the Accessory state). The

white wire in the wiring harness is connected to this source.

Using the wire strippers, expose a 2 cm section of the wire. Twist the exposed end of the

white wire in the wiring harness to the exposed section of the source wire.
