NOTE:
All wires in this harness are black. A number is printed in at
the tip of each wire, corresponding to the numbers mentioned below.
IMMOBILIZER HARNESS
H3 3 Points of Immobilization
H3
There are 3 pairs of wires in the H3 harness (see page 7) that lead to 3 in -
ternal 20-Amp relays inside the 2310 control module. The relays function
as “
Normally Open
” immobilizers. Normally Open means that the each
wire pair (e.g., Wire-08 and Wire-09) are normally not connected together.
But when the system is Disarmed and then the Ignition turned on, the im-
mobilizer relay switches and connects the two wires together, allowing the
engine to be started.
(None of the immobilizer relays draw power until the
Ignition goes on while Disarmed.)
NORMALLY OPEN RELAY WARNING
When considering whether or not to immobilize the fuel pump and/or Ig-
nition lines, keep in mind that all immobilizer relays used in this 2310B
security system are “normally open.” This means that even if a thief kills
power to the security system, the engine still will be immobilized. Only
when the system is Disarmed and the Ignition is later turned on will the
immobilizer relays Switch Closed, allowing the engine to be started.
The potential problem is that if something undesirable were to happen
to the relays that are connected to the fuel pump and/or Ignition lines,
there is the possibility the relays could switch back to their normal state
of “open,” forcing an immediate shutdown of the engine even while the
vehicle is in motion.
The installer therefore assumes all risk of connecting to the Ignition or
Fuel Pump lines! KIRAMEK offers information on how to connect the
2310 to the Ignition or Fuel Pump lines in the event the installer abso-
lutely must connect to those points. HOWEVER, it is strongly recom-
mended for maximum safety that you choose instead to severe only the
Starter line at 3 different points (shown in Fig-12 on the next page).
This is almost as secure and makes for a much safer installation.
