Universal Harness Installation
Note:
Please ensure that the Driver Door is OPEN during the ENTIRE installation process.
Black Wire (one pair) - Ground
•
With the vehicle’s engine OFF, attach both the Black Wires directly to a chassis ground point or to a ground line
(chassis ground) by splicing directly to a ground lead or by using a poke and wrap method.
Red Wire (one pair) - Continuous Power
•
With the vehicle’s engine OFF, use the voltmeter to locate a 12-volt BATTERY lead and attach both the Red Wires
by splicing directly to the lead or by using a poke and wrap method. If attaching to a fused lead or using an in line
fuse (not necessary), verify that it is at least 5 amps.
•
To determine a true Continuous Power source:
1.
Ensure the Driver Door is OPEN
2.
Select a wire
3.
With vehicle’s engine OFF, use a voltmeter to measure the DC voltage on the wire. It should show 12 VDC or
higher.
Blue Wire - Switched Power
•
With the vehicle’s engine OFF, use the voltmeter to locate an IGNITION line with switched power and attach the
Blue Wire to the line by splicing directly to the lead or by using a poke and wrap method.
•
Do NOT use an inline fuse on this line.
•
Do NOT use accessory Power.
•
The red, black and/or blue wires can be extended by using the same gauge wire if needed.
•
To determine a switched power source:
1.
Ensure the Driver Door is OPEN.
2.
Select a wire.
3.
With engine OFF, use voltmeter to measure the DC voltage on the wire. It should show 0 VDC.
4.
Turn the key to the ON position. Confirm the voltage is 10 Volts or higher.
5.
Turn the key to the RUN position and while the vehicle is starting, confirm the voltage is 9 Volts or higher.
6.
Start the engine and while the vehicle is running confirm that the voltage on the same wire is 13.1 VDC or higher.
7.
Turn the vehicle’s engine OFF and confirm that the voltage on the same wire is 0 VDC.
