Connecting your wires

Now that you have decided where each component will be located,

you’re going to find the wires in the car that the security system will be

connected to.

IImmppoorrttaanntt!!

Do not use a 12V test light or logic probe to find

these wires! All testing described in this manual is described

using a digital multimeter.

Obtaining constant 12V

We recommend two possible sources for 12V constant: The (+) terminal

of the battery, or the constant supply to the ignition switch. Always install

a fuse within 12 inches of this connection.

IImmppoorrttaanntt!!

Do not remove the fuse holder on the red (H1/11)

wire. It ensures that the control module has it’s own fuse, of the

proper value, regardless of how many accessories are added

to the main power feed.
