Step 5: Hardwire Lead – Installing a Live Connection:
Locate the white “B+” wire found on the Halo hardwiring lead. Remove the excess plastic sheath
material to expose the cable. This exposed cable will be connected to the vehicles live connection.
Locate a positive (permanent) 12v power source close to the Fusebox and, carefully expose the live cable,
removing a small area of the surrounding plastic sheath, no more than 5mm in length.
Using a multi-meter; measure the voltage between the exposed area of the live cable (vehicle) and earth
(vehicle chassis) to verify a constant 12v.
Wrap the exposed cable of the Halo “B+” wire around the exposed area of the vehicles live feed several
times securing the connection. In order to further secure this connection, it is recommended that these
cables are soldered together and protected with adhesive electric tape.
Step 5: Hardwire Lead – Installing the Ignition Connection:
Locate the red “ACC” wire found on the Halo hardwiring lead. Remove the excess plastic sheath
material to expose the cable. This exposed cable will be connected to the vehicles l connection.
Locate a Ignition switched 12v power source:
In many cases a wire leading to the rear of the fusebox can be used.
Carefully dismount one of the fusebox housings so that the wires leading to the fuses are visible and
identify a 12v ignition feed cable using a multi-meter.
It is recommended that a thick cable is selected to reduce the change of damaging the exposed metal.
Remove a small area of the surrounding plastic sheath, no more than 5mm in length.
With the vehicle ignition off, use a multi-meter to measure the voltage between the exposed area of the
ignition cable (vehicle) and earth (vehicle chassis) to verify a 0v.
Start the vehicle ignition and verify the voltage once again, confirming a 12v source.
