3. If a retest alarm was used (for the hearing-impaired) disconnect ECU wire
6 (Pink) from the red (positive) wire of the retest alarm and disconnect ECU
wire 11 (Violet) from ECU wire 1 (Red).
4. Disconnect ECU wires 10 (Blue-Yellow) and 9 (Light Blue) from the wire that
was cut during installation (Wire 10 and Wire 9 are connected in series with
this wire). This wire was originally running between the ignition switch and
the starter relay or solenoid (depending on the make of the vehicle).
NOTE: Refer to Appendix 4 at the back of this manual for the wiring diagram that
includes an external relay.
5. Reconnect the two ends of the cut wire. Test the wire by moving the ignition
switch to the start position. The starter should engage. Once the connection
is checked, solder and heat-shrink the wire back together.
6. Disconnect ECU wire 3 (White) from the +12 volt or +24 volt source wire that
was found during installation.
7. Using electrical tape seal the part of the +12 volt or +24 volt wire that was
exposed during installation.
8. Disconnect ECU wire 1 (Red) from the continuous (un-switched) source of
+12 volt or +24 volt that was found during installation.
9. Using electrical tape seal the exposed part of the +12 volt or +24 volt source
wire.
10. If OBD-II was used:
A. Disconnect the OBD-II connector of vehicle from the OBD-II cable
assembly.
B. Detach the female OBD-II connector that was mounted to the vehicle
panel.
C. Mount the vehicle OBD-II connector to the vehicle panel (its original
place).
D. Disconnect the 5-pin white connector of the ECU cable from the OBD-II
cable assembly.
12. Disconnect ECU wire 8 (Black) and the black wires from the alarm horn,
alarm flasher or retest alarm (if used) from the ground point (the connection
to the ground point during installation was made using a ring terminal and a
tamper-proof screw).
13. Ensure that all the wires that were cut and reconnected are soldered
together, then resealed with tape and heat shrinks.
14. Solder all connections. Shrink-wrap, tape and neatly tie-strap them.
15. (If used) Demount alarm flasher and alarm horn.
16. Reinstall all vehicle panels.
17. Perform a final inspection. Ensure that vehicle is returned to its original
appearance.
