Finding the wires you need

Important: Do not use a 12V test light or logic probe (com-

puter safe test light) to locate these wires. All testing described

in this manual assumes the use of a digital multimeter.

➤

Obtaining constant 12V

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

the battery, or the constant 12V supply to the ignition switch. Always install a

fuse within 12 inches of this connection. If the fuse will also be powering other

circuits, such as door locks, a power window module, or a Nite-Lite® headlight

control system, fuse accordingly.

Important: Do not remove the fuse holder on the red wire. It en-

sures that the control module has its own fuse, of the proper value,

regardless of how many accessories are added to the main power

feed. .

➤ Starter wire

The starter wire provides 12V directly to the starter or to a relay controlling

starter. In some vehicles, it is necessary to power a cold start circuit. A cold

start circuit will test exactly like a starter circuit, but it does not control the

starter. Instead, the cold start circuit is used to prime the fuel injection system for

starting when the vehicle is cold.
